Should I Report My Chronically Late Coworker? Impact on Team Projects

A 29-year-old marketing worker is stuck watching Sarah, a coworker who’s late by at least 30 minutes almost every day, slowly wreck the team’s deadlines and morale. It’s not one bad day or a weird week, it’s months of traffic excuses and oversleeping, with the same pattern playing out on repeat.

Every time Sarah strolls in late, the rest of the team has to scramble, cover for her, reshuffle schedules, and sometimes even redo work because she missed the start. The situation finally hit a breaking point when her tardiness delayed a major client presentation, and the client was visibly unhappy, which made the whole team look unprepared.

Now OP is weighing whether to report Sarah to their supervisor, knowing it could land hard, while also knowing the team’s reputation is already taking damage.

Original Post

So I'm (29F) working in a fast-paced marketing firm, and we have this coworker, let's call her Sarah. Sarah has been consistently late for work by at least 30 minutes almost every day for the past few months.

This lateness directly affects our team's ability to meet deadlines on projects. We've had to cover for her, rearrange schedules, and sometimes even redo work because she wasn't there to contribute on time.

For background, Sarah's reasons for being late vary from traffic excuses to oversleeping. However, it's become a pattern, and it's affecting our team's morale and productivity.

We've tried talking to her informally, but she brushes it off and continues her tardiness. The breaking point was when Sarah's lateness caused a major client presentation to be delayed, and the client was visibly unhappy about it.

This reflects poorly on our team and the company as a whole. I'm at a crossroads now where I feel like reporting her lateness to our supervisor is necessary to address this ongoing issue.

I know reporting her could have serious consequences for Sarah, especially in today's competitive job market. However, I also feel that our team's success and professional reputation are at stake.

So AITA?

The Weight of Team Dynamics

This scenario highlights how one person’s actions can ripple through a whole team. Sarah’s chronic lateness isn't just a minor inconvenience; it’s affecting project deadlines and team morale. When you’re working in a marketing environment where creativity and collaboration are vital, every minute counts. The OP’s struggle to address Sarah’s tardiness underscores a common workplace dilemma: how do you balance personal accountability with team cohesion?

The OP’s efforts to address the issue informally show a commendable attempt to maintain harmony. However, as frustration builds, it raises an important question: at what point does informal feedback turn into a necessity for formal action? This grey area is where many employees find themselves torn.

That constant 30-minute delay is starting to feel less like “oops” and more like Sarah’s schedule has its own rules.

NTA - You're not a babysitter. If she can't be responsible, she deserves the consequences.

Sounds like she's taking advantage of your team's goodwill. Nip it in the bud before it affects your career.

Comment from u/thegreatunknown

Report it. If she can't show basic respect for her job, she needs a wake-up call.

Comment from u/randomthoughts22

Info: Have you considered discussing this with Sarah again before going to the supervisor?

The morale hit gets real when OP says they’ve had to cover for Sarah so many times that deadlines start slipping anyway.

Comment from u/sunflowerpower89

Maybe suggest solutions like flexible hours or remote work to help her be more punctual first?

It’s similar to the coworker-friendship mess in the case where a friendship collided with unprofessional work performance.

YTA if you don't report her. It's about the team, not just Sarah's feelings.

Comment from u/cookiesandcream

Totally NTA. She's jeopardizing your team's success, and that's not fair to everyone else.

Then the client presentation gets delayed, and suddenly Sarah’s lateness stops being an internal annoyance and turns into public embarrassment.

NTA - She's impacting your work and the company's reputation. It's a tough call, but you have to think about the bigger picture.

Comment from u/anotherdayanotherdollar

Your team's success matters. You're not wrong for wanting to address a problem that affects everyone.

Comment from u/blueraspberry

NTA - It's a tough situation, but sometimes tough decisions are necessary for the greater good.

After Sarah brushes off the informal talks, OP is left deciding if a formal report is the only way to stop the damage.
