Apparently, since I left yesterday for a doctors appointment, I missed a real life loud flounce!
We have two groups of workers on this (related to mine, but not the group I work in) team. Employees - full time, on the company payroll - and contractors - full time, but on a temp company's payroll. Because of local laws and internal rules about not treating contractors as employees, contractors don't go to all of our staff meetings, or only parts of them, they aren't generally included in luncheons and such, and they are most emphatically not included in our corporate recognition program (which gives out gift cards and swag for people that go above and beyond). This last point is crucial.
One of the contractors, who admittedly is high producing (she also works a LOT of overtime, so this is part of the reason she does so much volume of work) was in the team's weekly progress meeting, along with everyone else on that team. They normally do recognition at a separate, employees only even, but there were two smaller cards that were being given for top performers of the week, and the manager decided that she'd give them at this meeting without dismissing the contractors (this is an accepted thing to do, when the employees only part is short and non-confidential). This contractor decided that she was MUCH better than the two people that got these awards, and not only yelled at the supervisor that was giving the awards, but stomped out of the meeting and slammed the door.
She was walked out a few minutes later, with her complimentary cardboard box to carry her things.
