My Home away from Home.

Well here I am again, yet another weekend MOD shift. For those of you whom are not familiar with my position, I work for a hotel that requires that a Department Head serve as "Manager on Duty" on the weekends. This requires that you stay at the hotel from Friday thru Sunday afternoon. Now I do put in my fare share when it comes to MOD shifts, but this time my inability to say no has been stretched to the limit. I try and try to open my mouth and form the word NO, but for some reason it never comes out. Now don't think that my boss does not appreciate my efforts, he does. Oh but how I envy the other Department Heads that can say no guilt free. So any suggestions that you have on teaching Shannon the fine art of saying no and meaning it would be greatly appreciated.
