This, as we all know, equates to 15 working days. This provision for the annual leave entitlement in section 20 (1) and (2) does not make any exclusions to the entitlement – in other words, no employee is excluded from this entitlement and certainly it makes no exclusion based on maternity leave.ome employers have interpreted this to mean that, since the employee is on maternity leave, which is unpaid leave, the employee is then neither working nor is entitled to be paid – hence no annual leave accrues while on maternity leave.
