To be peed off with colleagues?

[NonsenseTalker]

I am a lunchtime supervisor at a local school and also volunteer there.
A few months ago I made a glut of cakes and rather than myself and family eating them all, I took the excess into the staff room. A few lunch ladies said that they wouldn't get a look in if they were in the staff room and next time, leave some in the dinner hall for them. I've since had requests for more so a week ago I took more in and left some in the staff room and some in the hall.
I'm now being called a bum licker and brown nose because I left some for the teachers!! Both teachers and lunch ladies requested more.
Am I missing something? Am I not allowed to leave cake for whomever I please?

The comments are coming from one person in particular (think 'popular' girl at school) but also my line manager. They stand whispering and then make a comment louder as I walk past but don't say anything directly to me.
they made sure to eat it all before saying anything
I don't want to get involved with whatever warped workplace politics they've got going on but it's starting to get to me now.
AIBU to be annoyed by this?

There does seem to be a them and us culture in a lot of schools with teachers on one side and the other staff on the other.

You did nothing wrong. But the lunch team obviously see it as 'them and us' and don't like people being fair.

It's their issue. Tbh it's workplace bullying and I would be putting in a serious complaint. Might not make life easier, but it sounds shit at the moment anyway.

YANBU i just wouldnt make any more and if someone asks why tell them that someone complained about it and leave it at that.

Actually knowing me I would just out and our ask what the problem is, in front of everyone. And ask why me taking time to make a few cakes for everyone was such a big deal to her.

But that's not the best way to handle it and wouldn't recommend it.

Are they 9?

What unpleasant behaviour.

Could you say something directly to them? If not, make a complaint. Horrible.

Agree with not bringing anymore in.
You're lovely for sharing the cakes but It seems that its more trouble than its worth, for you personally.

Some people will never be satisfied no matter how kind you are.

I'm definitely not taking any more in!

Miss Popular wasn't in today so nothing has been said but I am incredibly tempted to ask her why it's an issue if she brings it up again.
Thing is, she works in the school, not just as a lunch lady, so technically she's one of 'them' anyway!! I just don't get it.

If I was you, and I did happen to take more in - they would ALL go in the staff room.

Can't be doing with that sort of nonsense.
