I joined the company in September 2019, and my probation period was for 6 months until last month, i.e., March 2020. I informed my employer in March that I wanted maternity leave starting from the 25th of July. However, they informed me that they couldn't afford the cost, and therefore, I was not eligible for maternity leave. Additionally, they are withholding my confirmation letter because I am pregnant. I am unsure of what actions to take in this scenario. My performance has been up to the mark, yet my employer is refusing to provide me with the confirmation letter and maternity leave solely due to my pregnancy.
