A review of why fair play works, one particular story that caught my attention was this:
The Empire State Building was constructed in just 13 months, and that included the dismantling of the Waldorf-Astoria hotel that sat on the site. Paul Starrett, the builder, treated his workers rather well by the standards of the time, paying much attention to safety and paying employees on days when it was too windy to work. Daily wages were more than double the usual rate and hot meals were provided on site.
The concept is known as “efficiency wages”. Companies that compensate workers well and treat them fairly can attract better, more motivated staff. Unlike most construction projects, the Empire State Building had low staff turnover, and workers suggested productivity improvements such as building a miniature railway line to bring bricks to the site. But Starrett was not naively generous; he hired accountants to patrol the works, checking that all materials were accounted for, and staff attendance was recorded four times a day.
