Which type of employee/co-worker is worse in your opinion?

Lazy employees who don't do their job and pretend it was an accident then make a bunch of drama about other employees.

I prefer the angry employee. That's how you get a job done and on time.

I prefer angry employee because all the negative is out there, in plain view and on the record.

I hate sycophants and fake people.

I am surprised that nobody has mentioned the saboteur. The person that maliciously undermines others to preserve their image, clear the way for promotions and other perks, or flat out destroy competition.

I do admit the angry employee is more upfront and honest than the one who shows favoritism.

I'm lucky enough not run into either of these problems so really don't know which is worse. Everyone in my workplace must interact closely together in order to achieve the same goals. If performance is an issue, they are regulated to non-essential or medial tasks that are going to get done at the end of the day anyway.

For the first employee I also remember him lashing out towards a Hispanic employee in his 60's for being slow and making a mistake on something, a few years later the Hispanic employee told me he thought he was such an a-hole, the second employee wasn't really mean to the Hispanic employee but he wasn't really too fond of him either and treated him like he was a lesser person.

I'd rather deal with the second type.
