agree!
When i was pregnant, my boss (female, >40's, single) treated me quite well and always told me no need to bother minor tasks which would be deployed to someone else. But when my maternal leave was almost finished, she called me and warned me not to extend the leave any more. That really shocked me how could she 180 degree change herself. The worst was when i back to work, apart from much much work she left for me, she took me to her room once and blamed me seriously but with not ground at all. It's only the second day i resumed duty..that's really a hard time for me and i really suffered depression. Luckily i have a good husband and a warm family to help me through..
