Abstract
Utilizing existing survey data and calculated salary means for academic staff, an examination of two aspects of remuneration is undertaken. First, salary differentials between academic staff and second, the value of work undertaken outside office hours. Findings indicate that only a small proportion of existing salary differentials can be attributed to the number of hours worked. Second, a measure of exploitation by universities is calculated indicating that approximately one-third of salaries are ‘earned’ outside normal working hours.
