Traders in London have been recently pushed for a shorter work day. Currently, Europe’s trading hours are longer than many other regions in the world. For example, the markets are open for 8.5 hours a day in Europe whereas the markets are only open for 6 hours a day in Asia. Proponents of the shortened work day contend that by decreasing the work day, the trading industry can attract more diverse individuals with differing life responsibilities, such as women who are mothers. Additionally, supporters assert that shorter hours can improve employee well being and mental health.
