Part-time employee gets promoted above dismissive colleague, then ignores colleague's attempts to become friends: ‘I'm driving her crazy by gray rocking her’

A revenge in the shape of a promotion.

It's almost impossible to get along with all of your coworkers, and that is okay. You don't have to be best friends with the people you see every day at the office; you don't even have to be friendly. What you do have to be is professional.

That is the only must when it comes to a workplace relationship. It doesn't matter if you absolutely love or hate each other; if you have to work together, you have to be able to act professionally around each other, no work will ever get done properly otherwise. 

When the colleagues in the story below started working together, things between them went quite smoothly; they shared an office, bantered, and maintained a friendly vibe while also successfully working with one another. At some point, for some reason, the dynamic shifted, and one of the colleagues crossed the uprofessional line. Instead of respecting her coworker, this employee started leaving her out of meetings and conversations, ignoring her requests, and altogether became outright hostile. 

This led her coworker to consider looking for another job, but before she managed to do that, she was actually offered a promotion. This was a great opportunity, so the coworker took the promotion, which led her to a role that was ranked higher than her entitled colleague. Safe to say, the colleague was not happy about the shift, but she no longer had the power to disrespect her coworker. 

Instead of giving the entitled coworker a taste of her own medicine, the promoted employee decided to do the exact opposite. She acted entirely professionally, but never friendly, towards the entitled coworker, and showed her exactly how you're supposed to act at a workplace, even if you do not get along.

After being on the receiving end of the cold shoulder for a while, it was clear that it was getting to the colleague, who all of a sudden returned to the friendly attitude she had when these two just started working together. Unfortunately for her, it was way too late to take all her entitled actions back and return to being friends…
