Where the same duties are performed, employees are entitled to the same rate of pay. Different rates of pay can only apply if this is based on different lengths of service which are reflected under different salary scales, annual increments or other conditions of employment, provided that such salary scales have a maximum that is achieved within a specified period of time.
If an employee changes from part-time to full-time or vice versa, and the same duties are continued, the rate of pay should not be decreased. But, if there is agreement that the post and related duties are changed, new conditions, including different rates of pay, may apply.
If an employee is sent for training when s/he is not on duty and the training is obligatory, the employer must treat that period as working time and pay it accordingly.
