Tip your building superintendent this Christmas, they’re actually on the top 10 list of dangerous jobs in North America, like 10 spots above cops. I’ve done the job and it’s high risk of ergonomic injury, as well as accidents, and working alone makes it even more hazardous. You can get sick from the job, get crushed by garbage bins, electrocuted, poisoned, gased, burned, fall off a ladder or worse, and it’s low pay.
