Maternity leave...

I cant actaully wait to go on maternity leave. Im 30weeks... my work place is depressing..manager is a 2faced B****!! Gives me all the late night finishes.. knows im struggling with sciaticia etc.. even the boss higher up has told her its to much for me but she says its not.. slags me off to other members of staff. Im literally over it..just have to deal with it for next 6weeks.
