What a ridiculous comment. The teacher has no idea how much work she does?
Anyway, she is correct that if you have annoying parents who are only there to work with their own kids, they can be a drag. I sat through a PTO meeting listening to people complain about not being chosen as room mothers (they were drawn out of a hat which was open for anyone to come watch). Most wanted to be room mothers so they could go on field trips, but those that weren't chosen said they would drive to it anyway, which I think is wrong
and weird (cut the chord people). Field trips are tight operations so kids don't get lost and I'd be pretty ticked off if someone came in and interfered with the my kids' teacher's organization.
We have since done away with room parents because a few teachers had some very bad apples who gossiped, competed, and made it all about them. Every party became major drama. It was extremely stressful to the teachers to try and appease every parent while doing her JOB.
