The practice alone of organizing labor power against owners, irrespective of the demands, given the existing state of the world, is what is needed to show Class solidarity.
Simply showing class solidarity in order to kick off other strikes is valuable in and of itself.
Y’all really have to understand a general strike is coming.
A general strike means the labor class (you most likely), which is the group of people who do not primarily gain their income from passive investments, and are reliant on contracts that they don’t create or control which provide them very little control over their economic future, stop working in order to put extreme pressure on the group of people who do control those contracts and who do control capital.
Such a system is foundationally unethical, and should be Deconstructed as rapidly as possible with the expropriation of all that capital to the rightful owners: the people actually producing the value, and done in a way that’s not under duress, such that you do not have to take whatever dog shit contract is put in front of you
