"...Rosenthal talked about labor problems: severe overstaffing, with some workers doing jobs that are no longer necessary..." I learned that in one of the office buildings in NYC, there is one (sometimes two) custodians who press the elevator buttons and call out the next one to arrive. These are modern elevators with indicator lights above them. I learned it was because of a union requirement. I always liked the idea of unions, having learned about how workers were trampled on "in the old days". After moving to NYC, however, my opinions toward them became a bit more tempered.
