To be effective a general strike needs to be open ended, indefinite, until demands are met. We are not there yet, organizing some smaller ones is a good practice run perhaps, but just preparing for the real one.

In 500 bc, then 350 bc or so, the plebians of Rome had general strikes, decamping to a hill and refusing work until demands were met. One was a written set of laws as the rich were just making shit up as they went. Another was getting tribunes, every tribe got one and they could veto the senate, offer sanctuary, were sacrosanct, elected to one year terms. The second general strike expanded the tribunate.

The Peoples’ tribunes are the only reason their republic lasted for 500 years. Until the imperial boomerang came back on them as well, the tactics they used warring with other peoples were brought home by their own politicians.
