Dear Heather - Done Playing Nice

 Dear Heather,
 

I've been working with a new employee for a little over 4 months now, and I'm not sure why she was hired.  She's not learning anything, she's not completing anything, she doesn't do any work.  It really pisses me off, because I have to pick up her work, and whenever someone comes in the door, she runs to the back room so she doesn't have to deal with them.  I keep telling her that she is being lazy and that she needs to do just as much as everyone else, but she doesn't get the message.  I'm trying to tell my manager what a waste of space she is, but it's not working.  I tried even showing her where the girl messed up on something as simple as updating our Rent.com page and my manager told me that it's not my job to watch what she does, like I'm the one who is the screw up!  How can I make my property manager see just how bad she is?

Dear Done Playing Nice,
While I may agree with you that, in this industry, 4 months is a long learning curve, I really have to tell you, I find your tactics disappointing and uncomfortable.  We've all been there, trapped in a work situation with someone we find to be utterly incompetent who infuriates us to more of an extent than any other person walking the planet.  I challenge you to find a workplace in the US where this isn't the case, at least part of the time.  The thing to remember about the workplace, though, is that it's a lot like school.  You didn't have to be best buddies with everyone, but you had to tolerate them, no matter how stupid or annoying you thought they were.  I've said it before and I'll say it again: Jr. High never ends until you master the skills that you should have learned there.

Cruelty to your coworker isn't going to make the situation better. It sounds like you couldn't possibly notice if this person is doing anything right in their job because you're too busy noticing them screwing up and expecting the worst possible outcome every time. 
 
I hate to be the one to tell you, but the way you're going, YOU have a better chance of getting fired than she does, because you're maliciously attacking her.  It is every employer's responsibility to provide a non threatening workplace, and, sorry to be the one to break it to you, but you're bordering on harassing your coworker.  As harsh as it might have come across, your manager did absolutely the right thing in reminding you that watching your coworker isn't your job. 
 
In employment terms, people who are bad at their jobs eventually get frustrated with the work and leave, or they build up enough mistakes that they get fired, but it takes a long time to fire someone safely in America, which is why we sometimes work with undesirable team members for so long.  I will tell you, though, the some of the things that so get someone fired faster than being incompetent - being a Negative Nancy all the time, being a Terri Tattletale, or being a Nosy Nora. 
 
I suggest you take a personal day and use it to cool off, shake off the stress, and do your best to get past why this person irritates you so much.   After that, I'd say make sure you keep your nose behind your own leasing desk, and out of what your coworker is doing.  You'll be better off in the long run and you might be able to rebuild some of the respect that your manager may have lost for you.
 
Good Luck!
