In a nutshell- I work for a small company that is doing very well. 3 owners/bosses take home 500k a year each and take multiple holidays, company doing well etc. I'm a lowly employee so obviously not taking home the big bucks. Anyway, they are organising a work social but not footing the bill, is that acceptable? Trying to gauge whether I'm just being resentful or if it is wrong that they expect attendance but not paying?
