Specialization shows itself in another way, namely, in an inability to turn from one kind of product to another. There is a large bindery in New York where several periodicals are bound. A girl employed there complained of the irregularity of her work. “It seems pretty hard on a girl,” she said, “to have to stay home two days in the week and then have to work so hard the other days.” Her employment was due to the different methods of binding different periodicals. Two weekly magazines were brought to the bindery on Tuesday and must be mailed on Thursday. Hand folders and wirestitchers were needed to bind them. An engineer’s magazine must be bound between Tuesday and Friday. The work on this was hand folding, gathering by machine, and sewing by machine, instead of wirestitching. Another publication was brought from the printer on Friday and issued on Monday. It was folded by machine and wirestitched. On Friday evening and Saturday there was no work for a hand folder or an operator of the sewing machine. Wednesday was the busiest day in the bindery; two magazines must be completed for the mailers on Thursday. Overtime was usual on that day. This girl could fold by hand, fill the gathering machine and operate the sewing machine. She worked from Tuesday to Friday. The issues of the magazine had been smaller than usual and her earnings were reduced. She reported that at hand folding, if there were plenty of work, she could earn seventy-five cents or a dollar a day. For filling the gathering machine the rate was eighteen cents an hour or one dollar fifty-three cents a day. But there had been so little work that her earnings in the past three weeks had been: January 4th-10th, $3.19; January 11th-17th, $7.75; January 18th-26th, $3.21. If she had been steadily employed, she could have earned five or six dollars a week as a hand folder, or nine dollars and nine cents for filling the gathering machine. “There isn’t much chance for a sewer any more in magazine binderies,” she said; “you know nearly all the magazines used to be sewed, but now they are wirestitched.”
