“Guards in New York City’s museums spend most of their shifts on their feet – usually four to eight hours at a time. They should also be able to carry as much as 25 pounds, trudge up and down flights of stairs several times during their shifts, and jump, bend, and run into action if a situation occurs. … These days, many guards must also learn to use complex digital technologies to observe hallways and crevices and communicate with other guards quickly.” And their pay is less than half of New York state’s median wage.
