The structure was generally not publicly accessible, and employees' movements were closely monitored. Conversely, there were also many amenities for employees, including a library, auditorium, gymnasium, and medical and dental offices. There was also a recreational space on the roof of the home office's 23rd Street portion, and through the larger complex's extensive system of kitchens and dining rooms, the company offered free lunch to every employee between 1908 and 1994. Though the home office accommodated 14,500 workers by 1938, they were split up into different social hierarchies, with immigrants in service jobs, women in seamstresses' and cleaners' jobs, and native-born workers of both genders in white-collar jobs.
