If you work a job where you have a deadline and turn in your work earlier? You're getting MORE WORK! YAY!
Shitty workers who do nothing but goof off rarely get fired, so all the good works pick up the slack and for the same pay rate. Yay! Doing other people's jobs while they watch!
At my work, if you're good in your role, you literally will never get promoted because they want your skills to forever be in that position. Yay! No growth!
