Worker cooperatives are enterprises solely owned and democratically governed by their workers. Generally, employees join the cooperative by paying a fee, and each worker gets one vote.
Think of how many times you've done a job where suddenly policy changes to something stupid just so that company could squeeze a few dollars more. Netflix is an easy example, going after it's customers about password sharing and increasing its fees. Workers know this is bullshit but the board and the shareholders make the decision for easy profit.
Workers getting a say would not only make work meaningful as you are a literal part of the business (as opposed to merely selling your labor), it would mean better run, democratic ruled business operation.
