Nevermind that "the 8 hour work day" included your lunch hour at one point. With an average one-way commute of 30 minutes for my state (California), here's basically 2 hours of on-the-clock time you aren't getting paid for.
it was, for execs who don't want to pay fair prices for labor. but don't worry, we're waking up again and labor has the numbers on its side.
My company does this. if i start work at 7 i can stop at 3, 8-4, etc. Before we went widely WFH if you were in the office for 8 hours that was it. People ought to have been pushing back on the whole “8 hours is actually 9 hours” years ago.
