 Turnover meant delays and extra costs of training, and use of slow workers.In January 1914, Ford solved the employee turnover problem by doubling pay to $5 a day cutting shifts from nine hours to an eight-hour day for a 5-day work week (which also increased sales; a line worker could buy a T with less than four months' pay), and instituting hiring practices that identified the best workers, including disabled people considered unemployable by other firms.Employee turnover plunged, productivity soared, and with it, the cost per vehicle plummeted.
