The communal kitchen area and bathroom are two of the most hostile environments at the workplace. Sometimes, after a long week at the office, certain employees will have been pushed over the edge by simple faux pas everyone is guilty of. In that case, it's pretty easy to tell who has been at their job for just too long. And instead of politely confronting the offender, these employees will instead channel their frustration into the ancient art of passive aggressive notes. You never know when you're going to set off a fellow co worker with an annoying habit. Maybe it's common courtesy at the printer/copier, maybe someone didn't clean out the coffee carafe when they were done with it. Everyone has gotten lazy at some point and forgotten to refill the toilet paper, but when these things combine it creates a perfect storm for those employees who are sick of being there. Of course, when leaving notes some people still are able to maintain a sense of humor, but sometimes there's no room for jokes amongst all the angry expletives. Check out this list of disgruntled employees leaving funny yet passive aggressive notes to their colleagues, and feel good that you don't have to work with them!
