case in point. The law in California regarding overtime became more lenient to allow for flexible shifts. Before anything over 8 hours was overtime, but then employers didn't have incentive to put people on four 10 hour work days or alternating three and four day work weeks of 12 hours. California said "ok, you only have to pay overtime for over 40 hours per week." My company did implement some flexible shifts, but also continued to pay hourly workers on a five day 8 hour work week overtime for any hours worked over 8 in a day.
Also California made a change to allow more hourly workers to become salary. We continued to keep some of these re classes positions on hourly rates so they could earn overtime, but gave them the benefit packages that people in salary positions get (1 week more vacation and a bigger bonus).
I have a sad feeling that most companies only abide to the letter of the law, and will do what makes them most profitable, which by definition means less cost and human labor is usually one of the biggest costs for any employer.
