Hours of Work (Industry) Convention, 1919

The hours of work (industry) convention of 1919 was an agreement made between different countries to limit the number of hours people had to work in a certain industry. This agreement said that each country would make sure that people working in industry would only have to work 8 hours in one day. Eight hours was the maximum amount of time people could have to work, but employers could still choose to have workers work less than 8 hours if they wanted. This helped give people working in industries more time to relax and have a better work/life balance.
