Right now I am working part-time, but last Friday my boss offered a salaried position. However, I started interviewing with another company last Thursday because I do not enjoy my current job and have been job hunting for a while. I did well on the interview and they want a 2nd interview on Monday.
The problem is that my current boss wants an answer about my salary decision tomorrow (Wednesday). I really want to do this other interview, but they have not made an offer or discussed salary.
What is the best way to handle this situation? Is it rude to accept their salary and still interview with another company, then quit? Or should I tell my boss the truth?
