Cash-girls receiving $1.75 a week for work that at certain seasons lengthened their day to sixteen hours were sometimes required to pay for their aprons. A common cause for discharge from stores in which, on account of the oppressive heat and lack of ventilation, “girls fainted day after day and came out looking like corpses,” was too long service. No other fault was found with the discharged saleswomen than that they had been long enough in the employ of the firm to justly expect an increase of salary.

—Jacob Riis, How the Other Half Lives, 1890
