Some thoughts:
* In my district every elem. teacher is required to attend 2 PTO events throughout the year. These dates are assigned in August - PTO meetings, Talent Night, BINGO for books, Family Fun Nights. One of the nights is always the grade level family fun night which the Teachers plan and PTO pays for.
* I have four of my own children in the district, so, I do attend many events outside of school to see my kids but, I also make sure to support any of my students who are participating. That being said, my family is very busy and the thought of just showing up at an event to make an appearance would probably not happen for me. I bring home school work every night, respond to parents' emails or calls, work on grad classes, read the book required for our monthly preofessional mandatory book club, write reports, work on my portfolio that is due at the end of every school year, make special projects for my students: a picture CD in Dec and May, gifts for parents, christmas program events, finalize the month's book order, update my classroom blog, type and weekly newsletter, etc. All of this happens on my own time.
* My husband is an IT dept head, he gets paid triple what I make and has a high stress job. Also, expected to come in when called - at church, night out, the middle of the night. He often has late nights or eve meetings with people from DC. However, he does not bring home the work load that I do every day. Just trying to put into perspective how much a teacher is expected to already do outside of the classroom
* In a month I have 1 faculty meeting, professional book club meeting, 3 team meetings (all after school or very early in the morning), Professional dev. meetings (often start before school hours or go later in the day, parent meetings, three months a year I do parent teacher conferences for 30 students all after hours, plus my PTO obligations.
* I support the PTO in many ways: I always encourage my students and parents to attend the book fairs, shop at santa shop, attend family fun nights. This information is always in my monthly calendar and on the weekly newsletter in addition to what PTO sends out. I like to think that is extra encouragement for my families to attend. With my own kids in the district I also support through them.
* I love my job and I love my students. Since I live in the small town I teach in, I see families all the time and spend time talking with them, etc. But, I agree with PP that often it turns into a conference. Also, I would be really upset if someone was implying that I was not doing my job because I did not show up to a school social event. I think I am very dedicated to my students and their families but sometimes, even teachers need a break!
