I work in a mid sized company. Due to company policy, we're usually not allowed to have personal electronics at work (all electronics in the offices must be tested every year, it's a licensing / auditing requirement).
This time of year, it is really, really hot. The IT office I work in has air conditioning, but the marketing and order processing offices do not.
Currently, our air conditioning is broken and is (sadly) not expected to be fixed this week or next week (the inspection today revealed more extensive damage). After this, a coworker returns from vacation that is allergic to AC anyways, so using the air conditioning this summer is pretty much out of the picture for my office.
Right now my country is suffering a heat wave, and temperatures aren't expected to drop appreciably for at least another 2 weeks.
Since I work in IT (we also do the testing of the electronics), I was able to bring and get tested a personal desk fan for myself. (It was a favor for me last year and has since been grandfathered in.) At the start of this heatwave (a week and a half ago) I lent my desk fan to the marketing department (2 people), since they're sitting in a particularly poor office for heat management. Due to lacking blinders and the facing of the windows, their office frequently gets 4-5C hotter then even outside temperature. I was in there shortly yesterday and came out drenched in sweat. It's bad.
Now, since our AC is broken, I'd really like to reclaim my desk fan. Current temperatures make working in my office a massive chore and productivity is at an all time low due to the heat.
My first (straightforward) attempt of asking for the fan back went predictably poorly.
I want to know if there's any way or angle from which I can make that request without completly and utterly souring the relationship with the marketing department (I can just take the fan back, it's mine). Before I make enemies of my coworkers, I'm prepared to instead just eat the heat for the remainder of the heatwave.
