Should I be mad?

[coco-bean]

I just recently got promoted at my job to "floor supervisor", not like im getting paid anymore but now i just have authority and make sure things get done the way they need to be!But anyways I never really mind getting alot of hours because i need the money really bad right now, so everytime this "one" certain employee of mine needs the night off, she justs asks me and i work it for her! But for the last 2 weeks i've worked 3 of her shifts...so that means double shifts for me...open to close! No time to get anything done or spend time with my fur-pups! Then yet again she text message me tonight asking if i work at my other job tomorrow...which i do, and wanted to know if i could work my shift at the salon up until the time i need to go to work at petco! Im getting alittle upset because i feel as if my employee is taking advantage of me being so nice and working their shifts for them! I dont mind...but when this would be the 4th time in 2 weeks...i think thats a little much! should i be mad?
I know i should expect to do this from time to time, but at all the other jobs i've worked at, if someone cant work their shift they need to ask one of their fellow employee's and then go to the supervisor/manager and go from there, i just feel like she's taking advantage of me trying to help her out!
thanks in advance!

You are definitely being taken advamtage of, I would stop it right now. This person needs to understand that she has to work when told, not when she wants to. Just set her straight, and tell her enough is enough, no more mister nice guy!!

She's jeopordizing her on job by missing all these days. I think it's time you put your foot down. YOU have a life outside of work and deserve to live it.

I just feel bad, cuz the first time excuse was that her dog was going to be put down...so i TOTALLY understand and said okay...then to find out that her dog didnt get put to sleep til the next week...so she got a free-bee, then her aunt died...randomly....so i said okay understandable...the next time, she was sick or something....then this time..(her this weeks excuse is, she has a brain and jaw problem) and she needs to go to the dentist to talk about fixing her jaw! her brain problem is a little odd to me...she said her left side doesnt respond like it should...but it does!!! there's nothing wrong with her left side! I've learned if im right handed...my right side is stronger and my left is weaker...just because i dont use it as much!
and MAGICALLY she is right handed...and all of the sudden she has a brain problem with her left side! weird huh?

I'm sure she doesn't work every single day, during the hours of doctors/dentists offices, etc.. she can schedule her appointments for more appropriate times.

Don't be quick to judge the absence of a medical condition by appearance.

Well at my last job, if you had a medical problem and had to leave work or change your hours you needed to show prrof from your doctor. I think that this is what she needs, just so you can see if she has been telling the truth!

Im not going to tell her there's nothing wrong, but for a healthy teenager who seems to have "alot" of things happen in a 2 week span is a little odd too me!
Did i already mention that within the same week she was hired she took COMPLETE advantage of her employee discount and bought some very expensive things throughout the salon!
She just seems like a typical teenager to me! I hope all teenagers everywhere arent like this because if thats the case, i have no faith!
