This could be done, but it'd need to be some kind of modern take on the old labor movement. People want 4 hour workdays, but they don't believe it'll change.

This could be done, but it'd need to be some kind of modern take on the old labor movement. People want 4 hour workdays, but they don't believe it'll change. Set up a site to allow people to specify their employer and essentially "opt-in", expressing their support for a 4-hour workday, but make it anonymous insofar as you'll only see a number of people at your workplace that share the same sentiment. There'd need to be some unique key to confirm that each person can only opt-in once. Compare the opt-in number to the number of employees reported on a company's tax paperwork, have the site get popular (whole project in itself unless there's good grassroots support), and suddenly you've got a nice obvious display of support within various companies for the 4-hour workday. Making it harder to ignore the will of the masses (or at least verifying that such a will exists) is a good start, I think.
