Well, to be perfectly blunt about it, some rosters are more tiring than others, of course, but when you knocked on the HR door, and asked if they had any openings for the pointy end, one might ask...were you not looking for work?
In this regard, hey...as Harry Truman once said, 'If you can't stand the heat, stay out of the kitchen.'
True then, true today....in spades.
