For Section 1- Does this bill regulate the amount of hours one can work for just one job? Or does this apply to multiple jobs? If the latter is true, how can employers enforce this? If an individual wishes to work the maximum allowable hours at 2 jobs (90 hours per week) does that individual get charged with a crime for breaking this law? Also, for high school students and those under the age of 18, 30 hours per week is still far too high a ceiling. 20-25 is more realistic, given that students need to focus on their schoolwork as well.
Employees can opt out. I think the point is employers can't force you to work over 45 hours/week.
It is relevant that these opt-outs must be approved by the Department of Labor. There are some industries where not all of these provisions will be feasible. Suppose a small town hospital has only one ob-gyn on staff to deliver babies; that person will likely need to work more than 12 hours in a 24-hour period.
