Employee refuses to cover for coworker Dina's absences after she blamed her for a shared project mistake, leaving her with a formal note in her file

How many workplace favors are you expected to do before enough is enough?

Most people understand that workplace relationships run on a mixture of cooperation, trust, and the occasional favor. Maybe you cover a shift for someone in a pinch. Maybe you can help explain a mistake before it becomes a bigger issue. Maybe you quietly look the other way when a coworker is running a few minutes late. These small acts of goodwill happen every day, and most of the time they're part of what makes a workplace function smoothly.

Of course, there's an unspoken expectation attached to those favors. Nobody keeps score, but people generally assume the support goes both ways. If someone helps you out repeatedly, you would hope they'd receive the same consideration when they need it. That's what separates a healthy working relationship from one that feels entirely one-sided.

The problem arises when one person starts treating that goodwill as something they're entitled to rather than something they've earned. Suddenly, favors stop feeling voluntary and start feeling expected. The coworker who once appreciated your help begins assuming you'll always be there to smooth things over, cover for them, or absorb the consequences when things go wrong.

That's why stories like the one shared by AlertShape5681 on r/AITH resonate with so many readers. The conflict isn't really about one meeting, one project, or even one comment made to a manager. It's about what happens when trust gets broken. Once someone demonstrates that they're willing to protect themselves at your expense, it's hard to continue acting as though nothing happened.

What's particularly frustrating is that people often label the resulting boundary as "petty" rather than acknowledging the behavior that created it. Refusing to continue doing favors for someone isn't necessarily revenge. Sometimes it's simply a reassessment of the relationship. If one person has shown they're unwilling to extend the same loyalty they've been receiving, the dynamic changes, whether anyone likes it or not.

At the end of the day, workplace goodwill is a lot like credit. It takes time to build, but it can disappear surprisingly quickly. Once a coworker has convinced you that they'll throw you under the bus when the pressure is on, it's difficult to blame anyone for deciding that future favors are no longer part of the arrangement.
