South Africa's economic prospects depend on the productivity of its labour, and productivity can only be maximised when the labour force possess the appropriate skills. Business is playing its part by offering training opportunities to employees. Collectively, they are spending more than the government's mandated level on training. However, the HIV and AIDS epidemic is eroding this investment in southern Africa where the HIV epidemic is at its worst. While there has been empirical work that provides estimates on the cost of HIV and AIDS to business, there is very little data on the actual amounts large companies spend on training, and how much of this investment is eroded as a result of HIV and AIDS deaths. Using an estimate of the HIV and AIDS death rate in the private sector and survey data which identifies training expenditure by sector, the authors estimate the extent to which HIV and AIDS has potentially eroded this investment. The loss for all sectors was estimated at almost R10 million (R9,871,732) during the study year, which equates to USD1,183,661 per annum. This amount represented on average 0.73 per cent of the actual investment in training. The real costs of HIV and AIDS on business, which includes absenteeism, declining productivity and other costs are difficult to quantify, but they are likely to significantly exceed this lost training investment as a result of increasing morbidity and mortality rates due to HIV. It is therefore in a company's best interest to: (1) ensure that a sound HIV and AIDS policy is in place; (2) invest in effective prevention programmes; and (3) provide the appropriate ARV treatment to infected employees if this treatment is not easily accessible through the public health sector.

South Africa's economic prospects depend on the productivity of the country's labour force. Productivity accelerates economic development and this improves the standard of living and quality of life of people (World Bank, 2013). Productivity is increased by two key drivers, technological improvements and human capital. Productivity can be enhanced by improvements in one or both of these drivers. In this paper the focus is on human capital.
The more productive the national economy becomes, the higher the personal income of employees and the lower the rate of inflation in the long run. When the economy increases its productivity levels it becomes more competitive and this tends to decrease the unemployment rate. The more productive an enterprise or organisation, the more income it generates. In this scenario, more jobs can be created. Since increased productivity results in the more efficient use of resources, it contributes positively to sustainable development. Productivity can only be maximised when the labour force possess the appropriate skills, hence the focus on addressing the level of skills within the country.
Recent concerns over the shortage of skills in the economy prompted discussions within the Joint Task Team (JTT) of the Joint Initiative for Priority Skills Acquisition (JIPSA) regarding the role that business plays with respect to education, training and skills development in South Africa. Businesses in South Africa are investing a large amount of resources into training their employees (Bhorat & Lundall, 2002). JIPSA grew out of the adoption of the Accelerated and Shared Growth Initiative (ASGISA) whose objective was to reduce the unemployment rate from 30 per cent to 15 per cent by 2014. Its task was to elevate the short supply of skills as an issue on the national agenda. JIPSA formed social partnerships between the public and private sectors to provide a strong base and respond to the economy's needs.
From a business perspective, training is offered to meet company development requirements by improving the productivity of the workforce. This investment also brings with it the promise of economic growth in the wider economy. The South African government has attempted to incentivise training within companies by offering a rebate to companies who spend an amount equal to the current one per cent compulsory skills levy.
However, HIV and AIDS is negating the effect of this investment in training. Information on the potential costs of HIV and AIDS in the private sector is vital if companies are to be given a financial incentive to invest in prevention and treatment interventions which could maintain or improve productivity levels (Rosen et al., 2004). The costs related to employee turnover, training and recruitment have been more severe for the mining, manufacturing and transport sectors than for the other sectors (South African Business Coalition on HIV/AIDS, 2005). It was reported that 23 per cent to 26 per cent of the mines, transport, manufacturing, building and construction companies surveyed indicated that they would probably appoint more employees (work shadowing) to compensate for the negative impact of HIV and AIDS on labour productivity, absenteeism and mortality. It should be noted that business cannot simply replace all those employees affected by the epidemic. In the period of 1 April 2006 to 31 March 2007 the mining industry was unable to fill 12 422 vacant positions (Mining Qualifications Authority, 2007). Most of these vacancies were for skilled technicians and trades employees, professionals, machine operators and drivers. These are the very areas that require large scale investment in training.
While there has been empirical work that provides estimates of the cost of HIV and AIDS to business in southern Africa (Rosen et al., 2004; Rosen et al., 2007), there is very little data on the actual amounts large companies spend on training, and how much of this investment will be eroded as a result of the high AIDS death rates experienced in South Africa and in working age groups specifically. Rosen et al. (2004) first attempted to calculate the economic impact of HIV on the private sector as a result of AIDS related mortality using actual cost data. These costs included sick leave; productivity loss; supervisory time; retirement, death, disability, and medical benefits; and recruitment and training of replacement employees (Rosen et al., 2004). It didn't include, through lack of data, training costs already expended on those employees who contract HIV, fall ill and are no longer productive. In the study, the cost of AIDS was calculated by combining retrospective data on employee demographic characteristics, absenteeism, productivity and medical care costs with unit cost information obtained from employment contracts, benefits policies and financial stakeholders and from interviews with managers. The AIDS related mortality in the workforce was estimated and the nominal cost per death was then multiplied by the estimated number of deaths in the year of the study, to obtain the aggregate costs of all AIDS related losses per year. For most companies the cost studies were conducted before the widespread availability of antiretroviral therapy (ART). With regard to the estimated cost of losing an employee to AIDS, calculated as the percentage of annual labour costs or 'AIDS tax' (in the absence of effective treatment), the cost was estimated to be 1.1 per cent in a large South African manufacturing company. For most of the other companies AIDS seems to be increasing the cost of labour between one and two per cent and seemed to not exceed three per cent for any of the companies studied (Rosen et al., 2004).
The aim of this study is to estimate the financial losses associated with the investment in training as a result of HIV and AIDS deaths. The paper further demonstrates the importance of prevention and treatment of HIV and AIDS in the workforce and those receiving training, to reduce company costs and maintain or increase productivity levels.
Using an estimate of the AIDS death rate in the private sector, and survey data which identifies training expenditure by sector, this article estimates the extent to which HIV and AIDS can potentially erode the investment in training.
2.1 Sample and data
The study was initiated by the National Business Institute, hence the majority of the companies surveyed were members of the Institute. All members were surveyed and it was decided to included members from other business working groups, which were the Big Business Working Group (BBWG) members and Business Leadership South Africa (BLSA) members. A total of 150 companies were surveyed, which included the top 100 listed companies on the JSE and the top 25 unlisted companies. Other than state owned entities (SOEs), the respondents were organised into sectors in terms of the standard industry classification codes (Central Statistical Service, 1993). This categorisation was as follows: manufacturing, community and personal social services, mining, financial, construction, wholesale and retail, and SOEs. The companies were then further analysed according to size: greater than 10,000 employees, between 2,000 and 10,000 employees, and less than 2,000 employees. Companies were approached and requested to complete a survey instrument, which elicited relevant information for the 2006/2007 calendar year period. A total of 106 companies responded.
Companies were requested to provide information on the education and training activities that they were involved in - their expenditure, the numbers trained, and the type of training received. Part of the expenditure on training included spending on individuals temporarily employed and not contractually employed by the company. These included individuals who were in an internship or on a training scheme with the company but were not considered as being permanently employed.
2.2 Survey instrument
The survey instrument was developed by the National Business Institute leaders, Robert Godsell (from Business Leadership South Africa) and researchers from the research firm Singizi who were contracted to undertake the study. The survey was designed to outline the training taking place within the private sector. It included questions on: (1) the total number of employees, (2) the number of employees that received in-service training and (3) the amount of money the company spent on training. The survey instrument is included as Appendix A.
2.3 Data analysis
Descriptive statistics used in the analysis incorporate cross tabulations which display differences in: employee complements, company spending on training and number of employees trained. A key component of the analysis was the calculation of the HIV and AIDS death rate in companies, which is demonstrated in the next section.
2.4 Calculation of prevalence in companies
Evian et al. (2004) suggest that the average HIV prevalence for the entire sample of 26 South African companies was 14.5 per cent (14.1-14.9 per cent) while Colvin, Connolly and Madurai (2007) report the crude HIV prevalence among the 32,015 participants, from 22 public and private organisations, in this study to be 10.9 per cent. The mean of these estimates is 12.7 per cent. Evian et al. (2004) found that among industrial sectors, mining (18.0 per cent) and metal processing (17.3 per cent) had the highest infection rates. Males, who comprised 85 per cent of participants, were more likely (16.3 per cent infection rate) to be infected than were females (10.7 per cent). Evian et al. (2004) go further and suggest that HIV prevalence of employees varies across job level or category, with contract employees having the highest HIV prevalence rate (23 per cent) followed by the un- and semi-skilled employees (18.3 per cent and 18.7 per cent respectively) with managers having the lowest infection rate (4.5 per cent). Colvin et al. (2007) confirm this view as HIV prevalence was significantly lower among managers compared with skilled and unskilled labour. Further surveys by Colvin and reported in Thurlow et al. (2009) and Matthews et al (2011) in the agricultural, manufacturing, tourism and transport sectors, show similar results to the above, with the exception of the agricultural sector. HIV pre-valence in the manufacturing sector was highest in the 35-49 age cohort with a reported prevalence rate of 24.7 per cent for managers, 27.2 per cent for skilled employees and 33.9 per cent for labourers (i.e. unskilled employees). The HIV prevalence rate for the age cohort 35-49 years was found to be significantly higher than other age cohorts, congruent with national HIV prevalence rates for males. In accordance with the region's generalised epidemic, HIV affects all groups in sub-Saharan Africa irrespective of their social and economic status. Level of education also plays a role in the likelihood of being HIV infected as the HSRC 2008 survey shows that Blacks with a matric level education were more likely to be infected (21.1 per cent) than those with no schooling (8.7 per cent) (Human Sciences Research Council, 2008).
2.5 Calculation of death rate in companies
The 15-49 year national age cohort was used in the calculation of the private sector HIV death rate. This is a commonly used cohort in most national HIV and AIDS studies (see HSRC, 2008; UNAIDS, 2008) because this cohort makes up the bulk of the working age population. Access to publicly available HIV prevalence data (Statistics South Africa, 2006), population data (Statistics South Africa, 2006), along with private sector prevalence data (Evian et al, 2004; Colvin et al., 2007) and an estimate of the number of persons that died as a result of HIV and AIDS in 2006 were used (Dorrington et al., 2006; Statistics South Africa, 2008). An assumption is made that a relationship exists between the upper- and lower- bound death rate. By using the above data, both rates are calculated. The mean of both these rates serves as the estimate of the HIV-related death rate in companies.
Prevalence is taken as being proportional to AIDS deaths. National death rates are given and are seen as having a relation to one another that can be used as the upper-bound rate.
The upper-bound death rate was determined by the number of deaths as a result of AIDS in 2006 (Dorrington et al., 2006; Statistics South Africa, 2008), against the 15-49 national population in the same year (Statistics South Africa, 2006) and multiplying it by 100 to give a ratio. The lower-bound rate was calculated by dividing the private sector prevalence (Evian et al, 2004; Colvin et al., 2007) by the national prevalence (Statistics South Africa, 2006) and multiplying it against the calculated upper-bound death rate. Prevalence studies were conducted between 2000 and 2006 (Evian et al, 2004; Colvin et al., 2007) so it was felt that prevalence was an underestimate of what prevalence would have been across companies in 2006 (hence its selection as the lower-bound rate). Using this, the following equation can be solved to determine the lower-bound death rate in companies:
with x = lower-bound rate = 0.57
Estimated private sector HIV death rate = mean of 0.57 & 0.81
Table 1 shows that based on this approach the estimated mean HIV and AIDS death rate in the private sector in South Africa in 2006 was 0.69 per 100 employees per annum.
2.6 Calculation of sector costs
Sector costs are calculated by determining the number of employees who would be lost due to AIDS using the mean death rate (0.69) and multiplying it by the unit cost of the training. Considering that the loss of a trained employee will result in a replacement employee requiring training, a 2007 training cost estimate has been calculated by taking current costs (2006) and adding inflation at 6 per cent (National Treasury, 2007).
3.1 Data from companies
A total of 106 companies responded with completed survey questionnaires. Table 2 provides an illustration of the companies by sector and size.
One fifth (n = 21) of the companies had more than 10,000 employees, 35 per cent (n = 37) of the companies had between 2,000and 10,000 employees, while 45 per cent (n = 48) of the companies had less than 2,000 employees. The largest proportion (37 per cent, n = 39) came from the manufacturing industry, followed by mining (19 per cent, n=20). Only two state-owned enterprises participated (two per cent of the respondents). Table 3 shows the number of employees by sector that participated in the study.
The mining sector (n = 262,148) represented the highest number of employees, followed by wholesale and retail (n = 192,832) and financial (n = 181,338) sectors. The construction (n = 29,252) and community and personal social services (n = 14,073) sectors represented the least number of employees.
3.2 Cost of training in the sectors
The results reveal that companies are spending on average four per cent of payroll on employee training.1 The largest amount spent on training was in the mining sector, which spent over R385 million (USD 46 million) with an average spend of R15,693 (USD1,882) per employee. The mining sector was followed closely by the financial sector, which spent more than R357 million with an average of R16,795 (USD2,014) per employee. The sector with the highest unit spend was manufacturing, which spent on average R21,593 (USD2,589) per employee. The lowest unit spend on training by sector was the community and personal social services sector, which spent R1,809 (USD216) on average. The average spend per employee across all sectors was R12,839 (USD 1,539) per annum. Differences in expenditure on training could be attributed to the types of training given, and any extra costs that may be included such as the cost of facilitation, equipment or venue hire etc.
3.3 Estimated loss of training investment as a result of AIDS deaths
The loss of investment based on the mean death rate of 0.69 is shown in Table 5.
Based on the below-mentioned estimation, in 2007 (a year later) the mining sector was expected to suffer the biggest loss as a result of the estimated HIV and AIDS death rate (R2,818,247), followed by the financial (R2,617,144) and manufacturing (R1,914,900) sectors. The total loss for all sectors was estimated to be almost R10 million (R9,871,732) during the study year, which equates to USD1,183,661. Using the upper-bound estimate (see Table 1), which is likely to be the case in higher prevalence sectors (see Evian et al., 2004; Colvin et al., 2007; Thurlow, Gow & George, 2009; Matthews, Gow & George, 2011) the total annual loss is estimated at R11,588,556 (USD1,389,515).
These estimates suggest that companies will lose on average 0.73 per cent (0.59 per cent and 0.86 per cent) per annum of the amount they invest in training employees purely as a result of HIV and AIDS-related deaths. While these figures may not seem very high in relation to the amount invested, it should be noted that the actual year-on-year loss due to HIV and AIDS will be significantly greater when absenteeism, productivity losses and benefit pay-outs are accounted for (George, Gow & Whiteside, 2009).
The reduction in overall skills and experience of the labour force, often referred to as a "generation gap" occurs when adults are forced to leave at a time when their productive capacity is highest and the entry of young, inexperienced and a less qualified labour force subsequently increases. Such employees are more difficult candidates for workplace-based training (Vass, 2003). Furthermore, reductions in highly skilled labour might not be replaceable in the short run. Quinlan and Willan (2004) caution against accepting the notion that the high unemployment rate in South Africa may suggest an untapped workforce for companies who experience high HIV prevalence rates. A less experienced and particularly young work-force might result in a decline in labour productivity. Continuous training is therefore crucial to maintaining the productivity in the private sector.
The results suggest that companies recognised the value in investing in their employees as companies were spending on average four per cent of their payroll on training. This indicates they were committed to spending over and above the legislated one per cent (Skills Development Levies Act of 1999). In comparison, companies in developed countries spent between three to five per cent of their payroll on training (Johnston, 2007). Private sector enterprises in Britain allocated on average two to three per cent of their payroll to training (Organisation for Economic Cooperation and Development, 1997). Employee training expenditure was therefore not only above the government levy in South Africa, it also appeared to be on par with expenditure in developed countries. Discussions with the surveyed companies revealed that their spending was unrelated to government's mandatory level and the amount that they are entitled to claim a rebate for, but rather based on the needs of the business. Additionally, they viewed this expenditure as an investment in employees which they hoped would result in increased productivity. Three things are clear in relation to this investment: (1) large companies were spending a sizeable amount of money on employee training; (2) this type of expenditure promises to bring benefits to both the company and the economy at large; and (3) a proportion of the investment in human capital from training would be lost as a result of HIV and AIDS.
The results suggest that while the annual loss of training-related investment due to the HIV and AIDS death rate within companies did not seem very high in relation to the amount the company was spending on training, the ripple effect of the loss of a trained employee was likely to be significant although difficult to quantify. These effects include the reduction in productivity from new employees that need to be trained, time spent on advertising, hiring and induction of new employees and the loss of institutional memory when experienced employees leave. The results suggest that companies should invest in HIV prevention activities to reduce future costs, although there is no means by which to predict the effectiveness of such an investment. Nonetheless, the results show that there is a need for intervention as the majority of the workforce is particularly vulnerable as they are in the age group most susceptible to HIV infection.
It is therefore in a company's best interest to: (1) ensure that a sound HIV and AIDS policy is in place; (2) invest in effective prevention programmes; and (3) where possible provide the appropriate treatment to infected employee if this treatment is not easily accessible through the public health sector. Rosen et al. (2007) indicate that without treatment it is only after about seven years that an HIV infected employee demonstrates declining productivity, absenteeism and other cost-increasing behaviours. After about 10 years the infected, untreated employee may retire due to ill health or die (ibid). Hence the effects of prevention and treatment efforts are not likely to be experienced immediately. However, the costs will be borne immediately. Further research indicates that through the provision of ARV treatment, infected employees remain productive (Larson et al., 2008, Thirumurthy et al., 2012) although it's critical that employees know their status (George, 2006) and that they are placed on treatment (Bhagwanjee et al., 2008) to optimise its effect.
From a purely economic perspective, the financial burden of absenteeism and employee attrition may transfer foreign investment to countries where labour is less affected by HIV and AIDS. This is likely to affect South Africa's economic growth and development. HIV and AIDS is also increasing the dependency ratio by decreasing the number of working-age adults (Vass, 2003).
Private companies should be recognised for the training they do and proper engagement with government, JIPSA and other such bodies needs to take place. If further support is given to companies by government then South Africa could train and produce a greater number of skilled employees whilst mitigating the impact of HIV and AIDS.
Along with providing opportunities for employee training there needs to be effective HIV and AIDS prevention and treatment initiatives which are constantly monitored and evaluated to establish the best practice for workplace HIV and AIDS interventions. In the absence of a clear understanding of HIV prevalence in sectors, on-going risk assessments are necessary to assess the extent of the threat posed by HIV and AIDS to the specific sectors and the companies comprising them.
Efforts need to be made to create awareness in companies of the potential impact of HIV and AIDS on their organisations and to create an understanding of why a proactive response is not only a responsible response, but also a response that makes good business sense. Support to companies to either offer HIV and AIDS services within or to partner with institutions or link to government treatment programmes that are able to assist them in this regard is vital.
Investments in employee training, especially by large companies, will assist in South Africa's economic growth. However, the returns of such investments are being eroded by the HIV and AIDS epidemic, especially in hard-hit countries like South Africa. It is therefore important for companies to put in place effective HIV prevention strategies and AIDS treatment initiatives to minimise the loss of this investment. These results are based on comparing investment in training in 2006 and the HIV context in the same year. It is recognised that whilst prevalence has increased since 2006 (HSRC, 2008), the AIDS death rate has fallen due to an expanded treatment programme (Actuarial Society of South Africa, 2008). Should training investment trends continue as witnessed in 2006, we would expect the financial loss, due to AIDS, to fall as a result of declining death rates.
