Don't forget the Support Staff.
And don't arrange a great FUN ACTIVITY TRAINING SESSION with cake baking and decorating competitions, a treasure hunt on the fucking unlit and multilevel site and party games, complete with award certificates if you're going to dump all of the actual setting up, supporting, clearing up, putting away, creation of the certificates, labels for the treasure hunt, printing of the clues for the treasure hunt and every other fucking thing onto someone in Support who ends up doing a compulsory 16 hours day and at least 14 hours of preparation work after completing their usual work hours in the run up, with no breaks, no, participation, no appreciation and no TOIL immediately without question/overtime paid without a quibble.
I might have been in this situation once, and I'll tell you, picking up individual cake decorations and confetti off the floor whilst overexcited NQTs are running around flicking cake mix at one another at 9.30pm doesn't feel like it does much for my fucking wellbeing. Especially when the person responsible got a huge bouquet and round of applause at the staff meeting for all her hard work.
And then bollocked me for not completing a batch of photocopying after I'd finished cleaning up, ready for first thing the next morning (when she'd left it on my largely unused because I was so fucking overworked desk nowhere near where I was already setting up the sodding decorations including fucking balloons - 15 minutes before the start of the Wellbeing Session).
