All work and no play makes Jack a dull boy...
(although apparently All play and no work makes Jack a mere toy...)
Lol. How about show up for your shifts and play when you're scheduled off instead of learning to screw over the people you were supposed to be working with. Or, here is an idea. Request time off for planned events, or ask someone if they can switch shifts to cover for you. Sorry won't be there for my shift because of something stupid like going dancing lol. I don't even want to waste my time and effort training someone like that. And doing it on their first schedule even doesn't bode very well for their reliability or responsibility.
Got a funny idea. Going to see if I can get a bunch of people to start posting on the schedule app. Sorry, can't work today, going dancing, thanks for understanding hahaha.
