Dear Samiksha Mayank,
What has happened to you is regrettable. You are already in or about to enter the last trimester of your pregnancy. Against this backdrop, commuting 40 km away is difficult. But then there could be more than meets the eye.
Informing the company about your pregnancy
Did you inform the company officials about your pregnancy? If yes, how did you inform them, whom did you inform, and what was the mode of communication? Ideally, the woman is expected to declare her pregnancy upon completion of her first trimester or even one or two weeks earlier. She is expected to provide a certificate from a certified gynaecologist. Did you provide the certificate to the HR Department, and if yes, did you route it through your HOD?
Possible motives behind the transfer
The second thought that comes to one's mind is the ploy made by the company's administration. Are you not in the good books of your HOD or the top "boss"? They know well that while in the advanced stage of pregnancy, it will be difficult for you to accept the transfer. Therefore, the option for you is to resign from the job. The transfer is nothing but an unsuitable condition created with a hidden motive.
Options available to you
You have a few options at hand. The first option is to accept the transfer. The second is to resign from the job. The third option is to apply for the deferment of the transfer till the completion of your maternity leave. The fourth option lies in the middle of the first two. You apply for the maternity leave with immediate effect. If you wish to resign, then you can give your resignation while proceeding on the maternity leave. In the resignation letter, you can request to treat the maternity leave as your notice period.
Thanks,
Dinesh Divekar
