In America, the legal system presumes you are innocent, but at work you are presumed to be guilty. Guilty of theft, guilty of tardiness, guilty of being unmotivated, unengaged, and full of resentment. Work assumes you are dishonest, that you will be always looking to cheat, to lie, that you are shiftless, lackadaisical, and lazy.
You are lazy. Now prove them wrong.
Management thinks the worst about their workers because they are typically incompetent, petty, and borderline psychotic. Think I'm exaggerating? Think about all the kind, caring, and decent bosses you've had.
Yeah, I thought so.
