What do you think about me calling in to work sick even though I'm not sick?
How do you feel when you call in sick to work, but you're not sick?
I don't really care because everyone does it.
While you may want to get out of doing work which is completely understandable, if you are caught then your boss will fire you.
I would consider myself to be a responsible employee, who exercises top-down decision-making.
You sound like a great employee, but being caught once lying could be enough for your boss to fire you. It's best to just take a day off instead of using a sick day.
