My mom works full-time and always has. When I first started elementary school, she was one of the very few that did. The homeroom moms would have meetings and things during the day, but she couldn't go obviously. So she was looked down upon by all the moms because she couldn't make it to every single party or field trip or event. I don't remember a single "parents day" type event that she missed, though. She was always at the mother's day picnics. In second grade, we had a lot of events like that and she went to every single one, except pasta day because that was for grandparents. When my brother started school, though, more moms were working, so it wasn't really a big deal.
