I work in an orphanage with lots of little children. I love my job but my supervisor is a nightmare. My supervisor pretends to be nice but she is super mean woman and has negatively affected my career, social life and marriage. Unfortunately I am unable to change my job at the moment because of circumstances beyond my control. I would like to notify my supervisor about my pregnancy not as a friend but as an employee.

How soon am I expected to notify my supervisor that I am pregnant?

Also does it depend on the kind of job I do? I care for the children.
