Boss wants me to work with difficult employee?

Get another job for the 7 weeks or just Uber for 7 weeks.

Record her, on your smartphone than Send the recording to the boss! If the boss continues to back her, record his conversation and go over to the next level!

Take a step up and have this employees difficult ness interrupt someone more important than you meaning some dome be who also has a say as to rather or not if this person can be removed.

Any stress blocks your brain from giving you right solution for any problem ,so whenever you have a problem that looks impossible for you to solve try to remove yourself from the problem . Right now you can not remove yourself from problem since you want that money ,so the only thing you can do is to speak to your boss again and ask your boss to give you solution for this problem ...because that is one of the things that boss is supposed to do . No ultimatums ....like "either she goes or I go" ... No , just say why is it difficult for you to work with her and ask your boss what she would do if she was on your place and do exactly that ,even if she suggest quitting job .Better to quit toxic job and not earn money than to have to spend earned money to heal health problems that occurred as a result of that stress .

Why did you not call her out on her rudeness and disrespect? By just giving in to her, you're creating a bigger monster. You don't need to be mean, just firm in your responses to her.

You tell the boss that you will not work with her either. In fact, being a teacher, I would draft a formal letter about it.

See, its one thing to tell your sibling you cannot employ their kid because they are trouble. Its another thing for an adult to draft a letter, which can then be handed over to this kid's parents. Coming from another 16 year old...no big deal. Coming from someone twice her age, who has experience dealing with kids, it should have some additional effect.

That's what I would do.

if u re a teacher and 32 haven't u learnt by now how to tune people out? let her talk and meanwhile do whatever u decide is worth doing and think of little kittens. or puppies - whatever u prefer. do not react on her behaviour, it is like feeding a fire

You SAY you are a teacher. So treat her like a student.

You are also her boss, and you are NOT related to her. So act like a boss and not a family member. Take control. Your boss doesn't have the balls to do anything about her, so he has pushed the problem onto you. Take control.

The girl sounds as if she has problems. Since you're just there as camp counselor and probably not earning a lot, it doesn't seem worth it to put up with her. I agree with don - tell the boss that the kid ruins your day and you're willing to endure that. Since you're the most experienced person there, I doubt they'd want to lose you.

Maybe they'll give her some sort ot solo , make work project to keep her busy.

Tell your boss you won't work with her. Stick to your decision. If he pushes it, tell him you are leaving and won't be back next summer if he makes you work with her.
