The history of labor is in this form of protest. Googlers are more comfortable than many others. The further down the chain you go the more precarious the workers and dependent on their pay checks, and the easier time management has retaliating. This stuff is legally protected because before we had legal protections, conflicts devolved into straight out armed struggle, with employers hiring mercenaries (notably the pinkertons) to break up employee resistance with guns.
