Shareholders need to start holding these companies accountable for strikes.

They only occur because the company refuses to negotiate in good faith. Strikes like this always result in billions of dollars of lost revenue over the course of the strike. By getting to the point of a strike, the company is choosing to fail their fiduciary responsibility.

After a strike is authorized, it's not going to magically go away. They either negotiate a new contract in a timely fashion, or lose billions until they end up negotiating anyway.
