Personally I think it's harder for me to work from home, too many distractions. Obviously a coworking space fixes this, but then companies have to pay for those as well. I'm also wary of companies using WFA options as "perks" to pay employees less: "We have a cool, work-from-home culture! Come work with us from your own couch! Save on gas, daycare, and time. Starting wage $15/hr." I'm not saying that to discount the good-intent from some employers that are actually trying to offer flexible work structures to their employees, all the more power to those employers, and good work.
