Are you old enough to remember what substitute teachers used to be like? When you walked into class and saw the substitute you thought, “This is going to be fun!”. When is the last time your employees felt that way?
Why not ask someone to be your sub for the day? I’m serious! It can be another manager or whomever. Instruct them to depend upon your team to let them know what is to be done...and then stay away.
Your employees will prove their ability to be self directed... they will get a good laugh...and they just might appreciate you when you return! C’mon, it’s summertime...loosen up a bit.
