As a newly unemployed individual contributor, I vote yes, because we're at the point where most businesses are too entrenched (or incompetent) to correct their business model. Well over 75% of the job listings I review have phrases like "Availability to occasionally work some evenings and weekends", which could mean anything from once a quarter to every single week, depending on staffing (or lack, thereof). Also, in multiple phone screens and interviews, I have heard the expectation of departmental employees working over 40 hours a week, even for locations with long train commutes. Just because I'm single doesn't mean I want to stay that way forever; I need to eat right, exercise, have a decent amount of life in my mythical "work-life balance", and so on.
We are past the point of companies regulating themselves in this matter; we need a law to enforce it. There are going to be many companies whining about lost revenue, but most of that revenue will come back to them in consumer spending, and frankly, it's the fault of the United States government for leaving these regulations so stagnant for so long.
