How could you suck at your career?

A sex worker.
You should suck good, but you blow.

Punctuality, is important to most jobs. Even if you are great at every other aspect…

Lack of attention to detail is huge when working with lots of numbers and programs.

And @MrGrimm888 is correct, showing up is half the battle, it’s amazing how many people can’t do that one thing.

Being stoned or drunk while operating heavy equipment would suck.

You could be a software developer who keeps making software versions that are more and more annoying, remove features and be less and less actually useful, and that spy on their users, require subscription fees, constant updates… oh wait…

Another thing you could do is go around biting your coworkers on the neck while muttering “I’m a vampire. I’m a vampire.”

@Dutchess_III They’re aware.

Lose your drive, your motivation. Get burnt out.

If you are a bank teller and you rob your customers with a weapon, instead of the white collar service charges theft, as they enter the store.

In a surgery a surgeon forgets to wash his hands.

A police officer who is robbed on duty , while armed, of his pocket change for his lunch money at the local doughnut shop.

Sens the boss Emails, I’m watching you!
Or what are you wearing right now?

You could get convicted as a felon. Or get a facial tattoo. Then, you’d never have a career in the first place.

Be a nanny and take the wrong kid home from the park.

Really bad speller and become a tattoo artist.

Librarian with Tourette’s.

You could be a President of the US and make fun of physically challenged people or make comments about sexually harassing women.

Present the wrong corpse in the chapel as a funeral director…
