1. I’ve earned it!
This is by far our favorite out of all 13 good excuses to miss work for a day. Admittedly, we’ve given you some decent and believable excuses to get a day off, but this one stands out, doesn’t it? Having worked overtime and stayed late at the office in the last couple of weeks, you more than deserve a single free day, and your boss is probably aware of that. If not, make him realize you’ve more than earned your right to not come to work today! Isn’t this simply the best reason for being absent from work?
