My point is exactly that the union didn't do what was best for its members because their actions collapsed the company.
Unions are subject to the constraints of operations. LTL is a very debt-heavy industry, and yellow pushed the envelop too far. But the union could have tried to negotiate a contract contingent on operating costs and debt load. They didn't. Instead they chose their line and then striked until the company went under.
Maybe not the best example, but it was the one on my mind.
> because their actions collapsed the company
The company blamed the collapse on their actions, different things.
Looking through the history of the company, it seems like the lack of making a profit for the last 25 years and taking on huge debt may have contributed way more to their demise than anything the union did.
