Your responsibility as an employee is to be ready for a full day’s work.  Too often, I see people who come in to work on Monday morning not really ready to work.  Maybe they partied too long on the weekend, or flew home on the redeye, I am not sure.

Your responsibility is to prepare yourself both physically and mentally for the workday.  Think of this way, would you go on an important job interview with bloodshot eyes and being over-tired from the weekend? Then why, after you get the job do you treat it with such dis-respect?
