janitors spend a lot of time cleaning up blood and other bullshit after shit has gone down or have to go into the dark maintenance tunnels for shit
they're a good target for changelings to murder and take their identity too because they can get access to almost anywhere with the excuse they need to clean in there 
also they can slip people with the water puddles they make and people get pissed off for being slipped and steal their no slip signs, beat them up, take their gear or hijack their janicart
