Is it part of the job I'm paid to do? Is it valid unpaid overtime of the sort that happens in any tech job, when the darn thing won't work and there's a deadline and I have a responsibility? Would I have volunteered to do it anyway? If none of the above, I'm going to tell you to shove it, in sufficiently polite but not in the least ambiguous terms. You think I'm a jerk? Poor team player? I can live with that.
