For workplace that engage in hostile behaviour against unionisation or collective action against a company. Talking to others may be a dangerous proposition to your livelihood.
Instead, you can try introducing them to an app, that allows for people to air their grievances.
If enough have issues, then a communication link between everyone can be conducted.
They can then start a strike threat campaign, which would send an anonymous letter to the target informing of the issue, how to remedy it, and how to contact the group.
If not solved by a deadline, a dice roll is performed. Each day it is not solved, would increase the probability of a strike.
If a strike is triggered, then everyone is informed of the plan.

The randomization is used to avoid strikebreakers.
The anonymous letter sending service is to preserve the privacy of the users.-- mofosyne, Mar 27 2015 YOU CAN'T ScARE ME https://www.youtube...watch?v=eAzhz29eVecim a stickin [popbottle, Mar 29 2015] It's a great idea, but the company might soon get wise to it.-- 21 Quest, Mar 27 2015 I like this idea. There should be a way of vetting people who claim to be workers, as managers/owners might install the app to spy or mess things up.-- the porpoise, Mar 27 2015 That's what I meant ^.-- 21 Quest, Mar 27 2015 random, halfbakery
