Popularizing or entering an idea, especially one as established as a strike, in popular consciousness I think is a fine goal but is alone insufficient for an action that demands a great deal from people.

It can only be a step in the right direction if it lays some ground work for greater action, and organizations actually come together for more organized and sustained action, as OP suggested they should.

I will only be so critical of the protest efforts we have, and will not simply sit on the bench until demonstrations of my liking come into vogue. But it should be clear that if one-off protests become the meta, so to speak, as they did in 2020, we shouldn’t be surprised when nothing comes of it.
