I've been in this exact situation. Fortunately I found another place to work in the same building that contained our office and I was super productive. I feel like the "no fun employee" but when you get shot 20 times a day from all the nerf Wars that break out I don't understand how anyone gets shit done. Ultimately they probably just don't (at least if it is as frequent as I ran into).
Wait, those seriously happen? I thought examples of that were just satire. I guess there are some upsides to working in finance. That would never happen there lol.
It used to happen in my office, but it was usually a friday evening thing, or in one of those awkward gaps after meetings, but before lunch, and everyone was distracted anyway.
I mean my 20 was probably an exaggeration but I can remember days where 10+ battles erupted around me. If it's 1 or maybe 2 times I don't mind and might even join in but on the days when it becomes excessive? I can't get anything done! Very frustrating.
