I am 5 months pregnant. I work for an employer who I don't think has to give me maternity leave. Is it true that if you have not been with the company for a year and it employs less than 20 employees, then they dont have to give you Maternity leave. I will be one month shy of a year when I am due and I am worried that I wont have a job anymore when it comes that time.
