Colleague Keeps Stealing Snacks at Work - AITA for Setting Boundaries?
AITA for confronting my colleague who keeps taking my snacks at work, which has led me to feel guilty and isolated in the office?
A 28-year-old woman refused to keep pretending her snacks were “mysteriously” disappearing, and honestly, the office snack drama has spiraled fast. One minute it’s granola bars and chips vanishing, the next it’s homemade cookies going missing too, and OP is left staring at an empty drawer like it’s a crime scene.
She tried the polite route first, mentioning it in the office group chat, but nothing changed. Then she started labeling her snacks with her name, and the situation finally hit a breaking point when she caught her colleague, a 34-year-old man, rummaging through the snack drawer and grabbing multiple items while she was working late.
Now he’s acting like the lock box is the real issue, and the whole office is suddenly treating OP like the villain.
Original Post
I (28F) work in a small office with a shared break area. For months, I've noticed my snacks disappearing—granola bars, chips, even some homemade cookies.
I tried mentioning it casually in the office group chat, but nothing changed. So, I started labeling my snacks with my name.
One day, as I was working late, I saw my colleague (34M) rummaging through the snack drawer and taking multiple items. I confronted him politely, asking if he could stop taking my snacks.
He seemed embarrassed and said he didn't realize they were mine. However, a week later, I noticed more of my snacks missing.
Frustrated, I bought a small lock box to keep my snacks secure. My colleague saw it and made a comment like, 'Wow, sensitive about sharing, aren't we?' This made me feel guilty, as if I was overreacting.
Other coworkers also teased me about it, saying things like, 'Better watch out, she's locking her snacks now.'
Now, I feel like the odd one out in the office, and I'm not sure if I handled the situation the right way. So, AITA?
Establishing boundaries in the workplace is crucial for fostering a positive atmosphere.

OP’s snacks kept disappearing for months, even after she casually brought it up in the office group chat.
When she confronted the 34-year-old colleague and he claimed he “didn’t realize” they were hers, it should have been the end of it.
The concept of personal space in the workplace is often underestimated.
This office snack fight with your 34M coworker feels like a girlfriend drawing a line when her boyfriend’s parents’ household kept eating from their groceries.

A week later, more snacks were missing, so OP bought a lock box and the teasing started immediately.

Between her colleague’s “sensitive about sharing” comment and coworkers joking “better watch out,” OP’s boundaries turned into office entertainment.
In the context of a workplace snack thief, the importance of setting boundaries cannot be overstated.
If the snack thief can’t respect a named lock box, he’s the one who should be worried about being the problem.
