"Her shoes hurt? Well, your face is killing me." That'll get the point across, I'm sure.

Heel get the boot when they find he has no sole, and heel have nothing to shoe for it.

Hopefully you give your manager the flu, serves them right. Karma for making you work.

Best is to sneeze, cough and pretend to pass out several times. Infect as many people as you can. Then as you're asked to leave because you're too sick, go "But my shoes don't hurt"

The power of the boner.

Lick everything

If he's an asshole and you know it, spread the flu! If he's an asshole and you know it, spread the flu! Cough on his desk, don't wash your hands, hand him paper, do your best, if he's an asshole and you know it, spread the flu!

Spit in his coffee, sneeze everywhere
If he catches it, good
If innocent other workers unfortunately catch it, the whole workplace will call in sick

Actually forcing you to work when you're infectious is illegal. Especially if you work with the public, or around food. It could be a major health code violation.

That sucks I hope you feel better soon
