Abstract
The aim of this article is to determine the impact of in-house training (defined as any training
provided by firms in the workplace) on employee productivity, employee remuneration and net
employee productivity gains when diversity attributes of the workplace are taken into
consideration. The manufacturing industry of Gauteng Province of South Africa is used as a
case study.
Fixed-effect panel data estimations were performed in order to determine the diversity-based
employee productivity, remuneration and net productivity differentials of in-house training.
The results accentuate the important positive productivity, remuneration and net productivity
spill-over effects created by in-house training opportunities. The outcomes of the study also
confirm the importance of a workplace that is more gender diverse, racial diverse and in which
skilled and older experienced employees are retained if the productivity spill-over effects
generated by in-house training opportunities are to be enhanced.
