Whenever you are presented with a situation like this, always put off a decision until you have time to think about it. I was recently asked to become one of the specialty TMs for Modernization at my store. The request came out of the blue on a Friday afternoon. I told my ETL-HR that I wasn't initially opposed to the idea, but I would like to think about it over the weekend and I would give them my answer on Monday morning. I talked it over with my partner, weighted the pros and cons, and begrudgingly decided, at this point in time, I had to accept the offer. I told my ETL first thing Monday morning, yes, I would move to the new position. The only caveat I would give with this advice is if someone demands an immediate answer right then and there. That is usually a bad sign and my experience has taught me it is best to just say NO.
