Congratulations for taking the high road. It sounds like your concerns were heard by your supervisor and taken to the next level.

It's a total bummer that nothing got accomplished. It sounds like your coworkers have no trouble laying the whole heap off on you. Next time anyone says they have things on weekends, be sure to have something that you also have to do on the weekends, that you ALL have important things to do. Let's share fairly.

I wouldn't despair yet. It sounds like your supervisor sees the unfairness and wants to do something. Be sure that if no one else takes the initiative, that you pick whichever plan you want.

Good luck and hang in there.
