Yep, I would suggest that HER HOURS be changed to work until closing. Let the 14 year olds go home when they should.
Employees like that you have to beat at their own game.
Just like here at the office, their is this lazy girl, and she went to the dr(she’s pregnant)and lied about her job duties. Got the dr to write a letter stating she couldn’t work more than 40 hours a week(she keys on a PC all day). Thinking she would get to leave early on Fridays (if she got 40 hours earlier in the week). So, her bosses can have her work 9, 10, 12 hours a day. Then to let her go in 40, they adjust her hours on Friday. Instead of leaving early, she comes in late and leaves at her regular time.
She screwed up by not getting the dr to write, she can’t work more than 8 hours a day.
