I agree that people should be paid for that time.. but I'm also curious where the line is drawn? I left the city to work on a small town because my commute 5 miles/day was 15-20 hours/week. I suppose you can argue many jobs pay well enough to cover that... But people also work retail in those areas.
An ideal solution would be to spread out the cities -- encourage more remote working (though not like we currently see)... But in lieu of that, where is the limit?
Is employee parking, which is a 5 minute walk to the back of the lot, covered? I had a friend that works at a car factory... If you don't drive that manufacturers car, you park in lot B, an extra minute or three away. Is that any different then being forced to stand at the for to leave a few minutes now and then? (It's not always 5-15 minutes, where this example is a constant).
Please accept this as a thought experiment... Not a criticism against better pay for retail. Everyone deserves the pursuit of happiness.
