Salaried employees are the most overworked employees in our society, so what's the point in making this change if it doesn't benefit the people who are really suffering from overwork and burnout?
Because this bill is not about overworking salaried people who are getting benefits. It's about making things fair for hourly employees who are being overworked without benefits.
Salaried employees being overworked is an issue a worker needs to take up with an employer directly. When you take a salaried position it is your responsibility to agree to the pay and the work hours. If hours exceed what you agreed upon when joining the company, and it becomes too much, you find another job. This is how everyone in my personal circle has ever handled this kind of situation of being overworked. If your boss/company isn't willing to either give you a raise or stop expecting such long hours, you walk.
