So, here is my problem.
Right now I am a third year student at the bachelor program. I landed a job of my dream and it turned out so that the employer in the case is my lecturer, he is very young, just 4-5 years older than me. I really in deep love with the job and I really need money. I am living in the dormitory with two other guys who are just interested in the same things as I do, but have different attitudes and values. They do not know that I got a job and if they will get to know it, then they inevitably ask the lecturer to employ them as well and I do not want to work with them, it will be very uncomfortable for me and I will stop getting pleasure from the job and will hate every minute of it. So I am thinking about asking the employer not to employ them in the case they ask about it. I understand that it may be very selfish, but in my case it will be impossible to find a better job than that one.
So, is it acceptable for me to ask my new employer not to employ these people? What the employer may respond in the case? How can I tell that to the employer? Should I ask it to be a private matter, so that no one else know about the conversation? How can I start the conversation if I am very shy about the problem to be discussed?
If it is not an appropriate place to ask such thing, then, please, tell me where I can ask it.
