So I work in a team of 8 people, one is male and the rest of us are female, everyone has children apart from me. I am increasingly asked to do tasks which are other peoples responsibility because they need to happen first thing in the morning or last thing in the afternoon and other people need to school-runs or have childcare issues. This morning I had to leave 90 minutes earlier than usual to do something for somebody else because she had to take her child to school. A few weeks ago I had a similar journey because the person was heavily pregnant and "just couldn't do it". We work on flexi time so whilst we have core hours the nature of the work sometimes means we need to work extra hours, which we are credited for. This is mentioned when we are interviewed for the post but it irks me when people can't do it because they're parents.
For the record I don't mind helping out as we are an industry which naturally attracts women of child baring age and I appreciate it's difficult, but lately it seems more of an expectation than a favour.
