Well in PHX they were serving full Thanksgiving dinners upstairs and down for all the employees. There was a sizable banner that featured a comical turkey and a message thanking employees for all they had done. I ended up eating way more than I should have, but that comes with the holiday. There's also the $500 (so far) this year in performance payouts, and those are kind of a thank-you I guess.
I think you misunderstand the meaning of Thanksgiving. It's being thankful for what you have, not insisting other people show how thankful they are of you.
They wouldn't be management if they weren't hassling people and trying to write them up; that's what they do. You'd think that for one or two of our most hallowed holidays people could suck it up and deal with it or refrain, but it just goes to show that some people can't resist any opportunity to complain. I'm not saying you're wrong, I'm just saying that there are times when no one wants to hear it.
