I appreciate this doesn't work for all jobs. But for those it might...
I have an unpredictable job that sometimes means working 15/16 hour days or through the night. I take time off in lieu if I work a weekend or bank holiday but recently I've been on a project that has given me the opportunity to work from home a day or two every fortnight. Wow. The difference it has made to my mental health and home life is incredible.
I'm no less productive at home - probably more so. Don't lose 90 minutes to commuting and am more productive when I am in the office as it is a change of pace. Why are we so tied to office based working now we have the Internet and so many people have phones/laptops?
Today, for example, I worked a 12 hour day, but I will work from home tomorrow giving me the opportunity to put laundry on and nip out to the post office during a 30 minute break.
