You spend a lot of time at work or, at least, communicating with your coworkers. And whether you're friends with any of them or not, you've probably gotten to know them a bit over the course of the time you've spent working together. You know who answers emails in the middle of the night, who you can count on to snag you a snack on someone's birthday, and who tends to sneak out early when the boss is gone. They know you too. But if you do these things, you're enabling your coworkers to take advantage of you, which isn't OK and likely isn't so great for your stress levels, mental health, or relationships with them.
When you know you're being taken advantage of and feel like there's nothing you can do to stop it, you can feel really powerless. But there are some things that you can do to put an end to it. In fact, you might even be doing things that are actually allowing it to continue, perhaps without even realizing you're doing so, which is why it's important to know what those kinds of things might be. Just because you might be doing things that are making it possible for them to take advantage doesn't let your coworkers off the hook for how they're treating you, but recognizing the role that you may be playing in the situation might also help you put a stop to it.
