I would mind my own business.
If you work under an employment contract protecting your job, I would agree with Iwire. It's the corporation's loss, not yours, and the corporate chain of command is usually adept at ignoring and papering over their losses. It is a game they are adept at playing.
With no contract, open shop or at will employment, the negligence, laziness, and shoddy work of the coworker will threaten your job and your next job. I could go into great detail, enough to just copy and paste to your own complaint.
If you want to work in the industry at a different employer, just put your time in, do not go the extra mile when requested, dodge the bulleeet, document deficiencies as they occur, but do not worry at all if nothing gets fixed. Your fix is to change jobs to a better employer, better industry posting. Don't let them hurt you while you wait and seek a better opportunity to move to.
If you want to stay where you are, I would advise fight and go scorched earth, that's what they will do to you so it's better to choose the same path they are on than to trust. The zebra does not change his stripes. The lazy do not suddenly get up and go, liars do not suddenly discover remorse and make amends. They take pride in their petty crimes.
There are some books on Amazon, expert ways to screw people over. Competent hacks will be reading from that manual, so hacking and dirty tricks come from the same hands. Don't know the titles but there's some famous ones.
You could be more screwed than you realize, thinking you can have him fix his work, but depending on circumstances, the hack and his allies, management, could be threatened by this disclosure and have real reason to fear for their jobs, hence the dirty tricks. Write some emails escalated up, and someone could fear disclosure of this incompetence for liability, their own firing, and take preemptive action to place the blame anywhere else, even back on you.
First try to find some allies on the job who can back you up with management. The hack is probably already beating you at this, sucking up to management expertly.
Your problem has recurred at every jobsite incessantly through history. If you want to gain a clearer understanding, insight, the books are already written, better, more than I could imagine.
Post a few details if you feel you can do so anonomously. If your company is big enough to have a HR or legal dept, do not post the details on a public board, post your complaint to your company's ethics hotline as a whistleblower.
There is a way to play this game to your advantage, but I do not know what that is. Keep the job, if they treat you badly, be sure to do less. Fake it my friend, they are.
