Nobody's saying you're not allowed to hurt the business.
But there's a big difference between trying to damage trucks by walking off mid-shift, vs. not showing up for work the next day. The same as there's a big difference between stealing things from a store vs. boycotting a store.
We draw these lines for a reason. Nobody's suing workers for going on strike. They're suing them for leaving drying cement in their trucks in the middle of their shift.
If workers simply finish their shift before going on strike, that's not crushing workers' right at all, nor is it creating a power imbalance that favors the owners.
