I was helping a teammate investigate an issue he is working on, while having a lot of stuff to do for myself, until I notice that the asshole was very busy sending personal emails and basically I was doing his job...

Hahahaha! I had a "friend " like that once. The worst part is that he took credit for my work and I was on with it because he paid me some bar bills and told me funny stories...
In the end I had an alcohol wage... thinking like that I don't feel bad anymore. Worth it.

@thiagoavadore I also had a "friend" like that... They are the worst

I had a similar guy in my team. Play cricket, football talks with friends.. doesn't know how to code.. not even a bit. He secured a Job in Singapore. Now he is looking ahead for US.
