You all deserve a massive pay rise, you're paid nowhere near enough for what you do. Personally I don't know how anyone can afford to be a TA these days without being subsidised with either another wage (evening/weekend job), or supported by a higher earning partner. It's such a shame that it has become such an unappealing role, pay wise. No wonder so many schools are understaffed and struggling to recruit. Something really needs to change.
That doesn't mean a teacher can't bemoan their own wages though. For the qualifications required, the hours put in and the responsibility involved, it's really not great pay these days (and yet so many away from education assume it is).
Moaning about our own pay doesn't mean we don't appreciate how poorly TAs and other support staff are paid for the amazing job they do. They are different roles though, so the two aren't comparable in that sense (except for the fact I believe your pay rises should be in line with that of a teacher's, in terms of percentage). Both roles are underpaid for what we actually do, and we're all equally entitled to feel aggrieved by that.
It's a good job none of us are in it for the pay, right?
I don't think anyone should be guilt tripped for admitting they feel the pinch, even if they know they have colleagues who are paid much less. Everyone's personal financial situation is unique. For example, I have some TA colleagues who I know are better off financially than me, because they have a husband who earns well and an adult child living at home who contributes to the bills (for example). I would never point that out to them though if I hear them bemoaning their poor pay, because they are totally entitled to! Moaning about being underpaid and struggling to pay your bills doesn't mean you don't appreciate other people are struggling to, or that you don't feel other people should be paid more too for what they do. It's all relative.
