Siblings Work Dilemma: Should I Cover for Their Mistake?

A 28-year-old man refused to cover for his 25-year-old sister after she dropped the ball on a deadline at their shared company, and now he’s the one getting blamed at work and at home. This isn’t some random coworker conflict, either, it’s his sibling, the person he’s been trying to one-up since childhood.

Here’s the mess: his sister was responsible for a major chunk of a crucial project. She’d been slacking off, he warned her multiple times, then the day before the deadline she told him she couldn’t finish due to personal reasons. She basically asked him to do her work too, so his team would not get dragged down.

When her supervisor started questioning his “lack of support,” the whole family loyalty versus workplace responsibility thing exploded.

Original Post

So I'm (28M), and my sibling (25F) recently started working at the same company as me, in different departments. For background, we've always had a competitive relationship growing up, always trying to outdo each other.

Last week, there was a crucial project deadline approaching, and my sibling was in charge of a significant part of it. They had been slacking off, and I warned them multiple times about the importance of meeting the deadline.

However, the day before the deadline, they informed me they wouldn't be able to complete their part on time due to personal reasons. I was put in a tough spot because if their part wasn't done, it would affect my team's portion of the project too.

I tried to reason with them, but they insisted I cover for them and complete their work as well as mine. Feeling frustrated and overwhelmed, I refused to cover for them.

I put in extra hours and managed to finish their part just in time for the deadline, but it took a toll on me. My sibling's supervisor found out about the situation and questioned me about my sibling's lack of contribution.

Now, my sibling is facing consequences for their actions, and they are upset with me for not backing them up.

They think I should have covered for them without hesitation. I understand their perspective, but I also feel like they put me in a difficult position by not taking their responsibilities seriously.

So, Reddit, WIBTA for refusing to cover for my sibling at work after they messed up a project?

NTA. Your sibling needs to learn to handle their own responsibilities. It's not fair for them to expect you to clean up their messes.

Sounds like your sibling needs a reality check. NTA for not enabling their irresponsible behavior. Family or not, work is work.

YTA. Family should always come first. You could have helped them out this time, and then had a serious talk about accountability.

Comment from u/musiclover9000

NTA. You did what was best for the project and your team. Your sibling needs to take responsibility for their actions.

The real twist is that OP isn’t just protecting his own work, he’s trying to keep his team from getting blamed for her missed portion.

ESH. It's a tough situation, but family dynamics can be complicated. Maybe find a middle ground to support without enabling.

This also echoes the cousin drama, where someone refused to sacrifice their plans to cover a shift at the family business.

Comment from u/adventure_seeker12

Your sibling needs to grow up. NTA for not covering for them. They need to face the consequences of their actions.

Comment from u/rainbow_dreamer

NTA. Your sibling's lack of professionalism shouldn't drag you down. It's important to set boundaries in the workplace, even with family.

Then her supervisor finds out, and suddenly OP’s refusal to cover her mistake becomes a “support” problem, not a accountability issue.

YTA. Family should always have each other's backs.

Comment from u/whimsical_whale

NTA. Work relationships should be based on professionalism. Your sibling needs to learn to handle their own responsibilities.

Comment from u/guitar_hero55

Nobody wants to be the backup plan for someone else’s missed deadline.
