被lay-off

if you go to appeal, the employer needs to evidence that you are incompetent for this role of something else.

the critical is whether a mom-to-be is legally allowed being fired according to the local employment law.

if the law says a mom-to-be can not be fired, you got much advantage. but, is your employer knew that or not?

you'd better to find WHAT made your employer decide to kick you out?

dont be intimidated, it is your job and you got to fight for RIGHTS of yourself!
