She needs to do the work she's supposed to do.

Remember back in school, when you were assigned a group project, and there was an unequal distribution of work amongst group members. It's common for members of group projects to sit back and let one person take charge, leaving that person to do most of the work. It's frustrating when you care a lot about your grade and are willing to do whatever you need to do to maintain it, but it seems like none of your peers feel the same way. The truth is, your peers can tell by your vibe that you're not the type to drop the ball on a major assignment, so they rely on the correct assumption that you're not going to leave the project incomplete if they don't do their sections of it. 

You find the same personalities in the workplace all the time. They know their overachieving coworkers will pick up the slack, so they don't feel a sense of urgency to complete their work on time. They're happy to let someone else take the lead on their project, especially when their boss hasn't given them a specific list of tasks that they personally need to complete. If anything, this problem is worse in the workplace than in school. In school, your professor might ask group members to anonymously report how the work was divvied up or whether anyone didn't contribute at all. At work, you're not going to get a failing grade for not getting your work done on time. A lot of times, you can get away with it for way longer than you deserve, because it's not socially encouraged to call out your coworkers for not getting their work done in front of your boss.

  • Am I the bad guy for refusing to finish my coworker’s work after she missed a deadline and expected me to cover for her?

    I work in a small office where most of us share tasks pretty closely. One of my coworkers tends to leave things unfinished and assumes someone else will sort it out.

  • Most of the time that ends up being me, mostly because I like things done properly and I do not enjoy loose ends sitting around.

  • Last week we had a report due that required input from both of us. She said she would handle her portion by Thursday.

  • Thursday passed and nothing was ready. On Friday morning she casually mentioned she had been busy and asked if I could just "fill in the gaps" since I am better with details.

  • That irritated me more than I expected. It was not just about the report, it felt like a pattern where my reliability was being quietly taken advantage of.

  • I told her I would not be completing her part and that she needed to finish what she agreed to do.

  • I tried to keep my tone even but I did not soften it much either. She seemed surprised and a bit embarrassed.

  • Later that day she stayed late to finish it herself. Since then things have been slightly tense.

  • I understand that people go through things, but I also feel like I set a reasonable boundary.
    via u/isabellaturner94
  • Still, I keep wondering if I came across as unnecessarily cold when a softer approach might have worked just as well.

  • Am I the j for refusing to step in and for how I said it?

  • auroracook72 She relied on you picking up the slack and got used to it. That kind of pattern only changes when someone draws a firm line. NTJ

  • laylascott62 The fact that she stayed late and completed it shows she was capable the whole time.

  • That_Ol_Cat NTJ Standing up for yourself can be hard, because you don't want to be the "bad guy." It can also be hard because you just want to set boundaries, not emotionally beat someone else up. Your coworker may have wondered why the change, or she may have realized how much work she puts you through with her habits. Well done on your shiny spine!

  • Aromatic-Beyond-9998 You were being a doormat. People liked that and took. advantage of you. Then you stopped and created a boundary. That tense, awkward energy is your new boundary working.

  • EffectiveSky3378 NTJ. "Fill in the gaps" is such a cute way of saying "can you do my missed deadline for me?" You weren't cold, you just stopped being the office safety net.

  • SundayEmpress "slightly tense" is not a bad thing! She caused it, you upheld a boundary and of course she isn't thrilled. But her being thrilled is not the goal, fairness is. Don't take her pouting as a sign that you did wrong! NTJ

  • Wonderful_Ad_6089 NTA for what you said or how you said it. The nonchalant way your coworker waited till the last minute to bring it up and just assumed you had done it is ridiculous. What you said was professional and straight to the point. If you had been any softer with her, I don't think you would have gotten this result. I think you would have gotten an attempt to guilt you into doing it. So good job standing up for yourself! If she's really an okay person who doesn't normally do things lik
