Don't worry about organizing anything officially. Organizations are too dangerous. They get infiltrated, demoralized, subverted, decapitated, and destroyed. Small cells and individuals can keep working when others fall.
A general strike can be very simple and relatively painless to the individual. Just show up to work, and don't accomplish much of anything of value. The OSS has a field manual we can use:

Organizations and Conferences
Insist on doing everything through “channels.” Never permit short-cuts to be taken in order to expedite decisions.
Make “speeches.” Talk as frequently as possible and at great length. Illustrate your “points” by long anecdotes and accounts of personal experiences.
When possible, refer all matters to committees, for “further study and consideration.” Attempt to make the committee as large as possible — never less than five.
Bring up irrelevant issues as frequently as possible.
Haggle over precise wordings of communications, minutes, resolutions.
Refer back to matters decided upon at the last meeting and attempt to re-open the question of the advisability of that decision.
Advocate “caution.” Be “reasonable” and urge your fellow-conferees to be “reasonable” and avoid haste which might result in embarrassments or difficulties later on.
Managers
In making work assignments, always sign out the unimportant jobs first. See that important jobs are assigned to inefficient workers.
Insist on perfect work in relatively unimportant products; send back for refinishing those which have the least flaw.
To lower morale and with it, production, be pleasant to inefficient workers; give them undeserved promotions.
Hold conferences when there is more critical work to be done.
Multiply the procedures and clearances involved in issuing instructions, pay checks, and so on. See that three people have to approve everything where one would do.
Employees
Work slowly
Work slowly.
Contrive as many interruptions to your work as you can.
Do your work poorly and blame it on bad tools, machinery, or equipment. Complain that these things are preventing you from doing your job right.
Never pass on your skill and experience to a new or less skillful worker.
Be patient, make noise online in anonymous ways. Keep going no matter what. When one job seems like they're catching on, start looking for another job before they become certain and fire you.
