A: Firstly, congrats on your pregnancy!
Secondly, you must be employed full-time for at least 12 months. If you meet that criterion, your protection lies under The Maternity Protection Act, 1998 of Trinidad and Tobago. Direct your boss to s.9(1) and (2), which states:
(1) An employee is entitled to thirteen weeks maternity leave and may proceed on such leave six weeks prior to the probable date of confinement as stated in the medical certificate submitted under section 8(1)(c) or at a subsequent date at the employee's discretion, and is required to return to work, subject to section 10, no later than thirteen weeks from the date she proceeded on leave.
(2) During the period of maternity leave, an employee is entitled to receive pay from her employer to an amount equivalent to one month's leave with full pay and two months' leave with half pay.
Good luck, and let me know the outcome!
