Show me the money! As shift supervisor, it's your duty to count the money in the cash drawer (sometimes several times a day) to make sure your team is staying on track. But that's not all.
During your day, you get to be in charge of the team. You'll be in charge of telling employees where they'll be working and making sure that everyone shows up to their shift. In other words, you are the team leader. If you jump off a bridge, so does everyone else.
Before you jump off the bridge, you should know that you'll probably only be working 30-40 hours a week. Which isn't that bad. Sure, it's not retirement, but you got to have something to pay the bills. And this sure will get the job done.
