I love this thread... Four pages and so far not one person has agreed with the op? Yet she's still going? You surely have to give her a few marks for perseverance?
OP - When I told my boss I was pregnant she hugged me, she sent gift when LO was born. When i suggested a kit day she said I was welcome to one if I wanted but that she didn't expect me to attend if LO needed me, she asked me to go into work to discuss a possible promotion on my return, she's keeping my cover on for an extra few months when I return so that there's some flexibility in our team. In short, she's been amazing.
When I go back next month (next month, yikes!) I'll be committed, focused and fresh. If I'd worked for you & heard your views on maternity leave I'd be looking to take my expertise elsewhere.
