Co-workers

It’s extremely frustrating when you feel like you’re doing great work but the ultimate outcome or grade is being weighed down by another person’s incompetence.
It’s one thing when an incompetent person reports to you – in that case you have some legitimate power to affect their behavior – but what are you supposed to do when you’re peers? 
* Do all the work yourself to make sure it’s good and then share the credit?
* Argue every issue and create an extremely tense working relationship?
* Give up and ask your boss to assign you a new partner?
* Do nothing and risk having a terrible outcome?
It’s a hazardous business. Any approach you take could backfire. These are your options:
Do nothing. Minding your own business might seem like a safe choice, but when your peer’s ineptitude comes to light, it might become apparent to others that you knew about it but did nothing. So much for being a good team player.
What do you owe the organization? Given the risks, why do anything? Is it really your business? If the person is affecting your ability to get your job done, then yes. And even if not, the person might be a waste of money at best, or others might suffer from his ineptitude. The organization as a whole may be suffering. If the first question encourages inaction, this one promotes action.
