They really use that terminology as they lobby for "donning and doffing" rules that give them extra pay for the time they spend slipping into their government-supplied garments.

Most cashiers are killed on the job because of homicides, whereas a quarter of firefighter deaths are from truck accidents – and the numbers have declined, apparently, after concerted efforts to convince these heroes to buckle their seatbelts.
