If the company culture is that managers buy their team an egg then you are being a little bit unreasonable. The goodwill you will get for spending £6-10 on some eggs might well be worth it. (I appreciate that isn't nothing to you.....but still think it worth it.)
This. I was in a similar position a while ago - I'm a union rep and some bad feeling arose about people not getting the usual chocolates/bottle of wine Christmas 2020.
Managers view - it's been a hard year for us, wine and chocolates for 6-8 people per team is quite a lot of money, we're not in the office like we usually are so how would we even have got them to people, delivery to 40 separate houses will cost more than the wine, nobody's ever very grateful for them anyway, the staff we manage are all on fairly decent wages so can afford to buy themselves some chocolate if they want some.
employees view - yes it's been hard, particularly for us as we, unlike management, were still expected to go out and meet the general public during the middle of a pandemic which is why when it's the hardest year we've ever worked it's upsetting to not even get the usual miniscule rewards we usually get, let alone something special to say thanks for us all going above and beyond while you've been sitting at home. Obviously we can afford to buy our own chocolate but it's the thought that counts. We've had our wages frozen, not having a christmas party so a tenner for a thank you isn't much to ask. Lots of other teams around the organisation have managed to get their staff presents delivered, and we've done a secret santa between us and sorted that so it's hardly impossible. You could have done a gift card or something if that was easier.
So although whatever the actual gift is can sound pretty petty, what your staff are thinking is "ffs she can't even be bothered to spend a quid on an easter egg for us to say thanks for working our socks off. See if I can be arsed to volunteer for overtime when they need someone next week."
Honestly from my experience, there are so many easy things managers could do that cost either nothing, or barely anything that would make their lives so much easier by showing they appreciate their staff and fostering a bit of good will, yet for some reason nearly all refuse to do it. It's tiny things like sending a card at christmas that is personalised to the individual for something they've done or are good at (can be an e-card or even just an email!), letting people finish ten minutes early once in a while, remembering their birthdays and saying happy birthday, perhaps buying something like a £1 chocolate egg at various times throughout the year, buying them a drink at the Christmas party, thanking and acknowledging people when they've done good work, letting them have a dental appointment once a year and not make up the time, saying "I'm sorry to hear that," and "I hope you get better" when an employee phones in sick rather than "oh are you sure? Will you be back tomorrow?"
