Workforce diversity is considered an indicator of successful diversity and equal employment opportunity initiatives. In Kenya, it is a legal requirement for all public establishments to seek to represent the diversity of the population in employment of staff. This study analyses ethnic and gender representativeness and heterogeneity of the workforce in public universities. The results show over-representation of certain ethnic groups and non-compliance with diversity requirements in most universities. Variations between universities with regard to workforce heterogeneity are not statistically significant. However, the link between workforce heterogeneity and degree of urbanisation of university location is statistically significant. The conclusion is that compliance with legal requirements does not necessarily translate into representativeness and heterogeneity of the workforce. A shift from legal compliance to planned increase in numbers of under-represented gender and ethnic groups through diversity initiatives that identify and address barriers to equal employment and discriminatory employment practices is recommended.
