Ask HN: What would be the effectiveness of a large strike of IT professionals?

It's common to see protesters and riots and hundreds of thousands of people marching for many causes. It often appears that the antidote favored by the unpopular is to simply wait it out, for its just some bad press and property damage right?

I wonder how effective a general strike by IT professionals would fair in terms of causing action amongst politicians which are most influenced by corporate donations?

My perspective indicates that nearly all revenue generating products I'm aware of at large enterprise fortune 500 companies seem to rely on a small round the clock teams to keep the engine running.

I often see teams which are mostly politically like-minded, who also meet the below criteria:

a) They have capital for extended time away without pay. b) Work in an industry that has a surplus of jobs, if they lost their employment. c) Have responsibilities which involve keeping critical revenue generating infrastructure functional and up to date

Obviously not talking about life-supporting infra, or intentional sabotage, just voluntarily walking out.

I like this community on HN as it's pretty level headed. Would a relatively small (< 10k people) walk out of like minded IT engineers put a large enough financial risk on the biggest companies, to effectively pressure a disfunctional government to change?
