One design for this subject, on a Unisex Standard T-Shirt. If more appear in the same line they will show up here.
The building only looks after itself if somebody is in early doing it, and this is for that somebody.
Trade and profession shirts are specific on purpose. Someone who says they are a janitor will not accept a near-miss title, and the closely related jobs each have their own version — that precision is the whole point of the joke.
One design for this job so far. Check the wording matches the title they actually use before buying.
Best for someone a few years into the work — long enough that the job has its own vocabulary and its own complaints. For a new starter it can read as presumptuous, and for someone who has left the trade it reads as nostalgia rather than a joke.
Nobody notices the work when it is done well, which is the defining feature of the job and the source of most of its humour.
They also hold every key and know every fault in the building, which makes them the most useful person in it.
The mess left the night before an inspection is a story every custodian has.
The wording only works when it names the exact job, so it is worth checking before you buy. Lawyer, Librarian and Lifeguard each have their own page with their own designs, and there are more below.
