When you're offered a position you dislike...

[Dionysus]

Whenever a job, chapter, or club, etc. offers you a position that you are overqualified, underqualified, not confident in, or simply dislike how should one handle it?

Should one turn it down? EVENTHOUGH that position will get you money if it's a job or more privledges if it's a chapter or club.

Should one take it and do one's job well so one will get promoted? I tried that once and it backfired, I did so well in my position that they didn't want to replace me.

Should one take it and half-a$$ed it so one will be offered another position? I tried this a few times and it also backfired. I actually lost an EC position and a job using this strategy. Instead of them offering me another position because I was dissatisfied of the current one, I was terminated from that position and job and was not offered another one. On the other hand, I was just offered a better EC position in my chapter, because I complained and slacked on the last one...but that was an exception.

What am I doing wrong? Is there another way around besides the above?
