Employee on fixed-term contract/temporary/part-time basis
An employee on fixed term contract, temporary and part-time employment is entitled to 12 weeks of maternity leave, if she satisfies the eligibility conditions under the Employment Act or 16 weeks of maternity leave, if she satisfies the eligibility conditions under the Children Development Co-Savings Act. If she is eligible for paid maternity leave, she will be paid at the gross rate for each day that she would normally have been required to work under her contract of service.
Employee on probation
It does not matter that an employee is on probation, as long as the employee has worked for the employer for at least 90 days before the birth of the child and meets the other eligibility criteria for maternity leave under the Employment Act or the Children Development Co-Savings Act.
Disputes
In the case of a dispute, the employee should first speak with the employer to understand the reason for dismissal. If she thinks that she has been unfairly dismissed, the employee can:
* Seek the union's help (if she is a union member);
* Seek legal help; or
* Submit an appeal to the Minister for Manpower within two months after the child's birth.
Employee's Obligations applies to employees under Employment Act or Child Development Co-Savings Act.
