Employees want to earn the same amount every month and everything in their life is based on that, rent/mortgage, bills, loans etc. Employers end up meeting this need by making employees work a set amount of hours a month. People typically can't deal with less or more money a month in sensible way. Sometimes there isn't much for employees to do, but that's a risk the employer either takes or should fix. Some employers have a flexitime system to ease this a little. The 9-5 is a result of those factors and there are alternatives, start a product business or do freelance work.
