I see it from the opposite side. This won't be employee-pulled, but company-pushed.

Many organizations are going to be significantly cash-strapped at the end of this recession. One of the juiciest targets will be cutting the high fixed cost of office leases. Especially in expensive areas like Silicon Valley. If a company can push the average employee to work from home 3 days a week, they can convert to floating desks and cut their real estate costs by 50% or more.
