Earlier quoted context omitted.
I'm not saying they shouldn't go on strike. I'm saying that they aren't on strike, as they're still working. Refusing to service one customer isn't striking.
It's just one company that doesn't play ball so a full strike wouldn't be appropriate reaction, especially as employers' organization apparently isn't a participant here. Say, striking dockworkers can paralyze the whole economy, all sectors. It's not a step to be taken lightly.

Well, there's no balancing downside to doing it this way. Workers still get paid. So they can do this pretty lightly, assuming their employers allow them to just discriminate against certain customers.
