I have a coffee mug on my desk. Every time I finish a can of soda, I pop off the top and throw it in the mug. It's a quirky way to represent how long I've been at this job.
I noticed someone stole it over the weekend. It has basically 0 monetary value (the mug was free too), but it does have decent sentimental value. I'm just not sure what the tolerance policy is of typical American corporate offices.
Even if I dig through the footage of a security camera around my cubicle and find damning proof of who stole it, would anything even be done? The stolen article is worth nothing, but would it still be a fireable offense? My only concern is that I do some investigation, and HR and other managers on this floor are like "so what?", and I get pinned for overreacting. I just want to double check that I'm not being unreasonable for raising an incident report and starting a whole process with security, HR, etc.
Edit: Reason I think someone stole it is that I've had other items like my macbook charger, board markers, etc. stolen from my desk when I wasn't there. Couldn't reasonably follow up on those since they happened before the security camera was installed. Also, I understand it's possible some cleaner just threw it out. But my question is how far I should go with it if I do find something in the footage of the security camera.
