I do understand that point too. But an agreement is not all one side or the other. It's supposed to be a comprise, so one side doesn't get all they want and neither does the other side.
And you should also keep inflation in mind, because the railroads aren't immune from it. So if it costs more to operate your business due to inflation and high energy costs. So under these conditions might the agreement be seen as a generous offer? I mean considering if the rail workers took the agreement, the business might be able to hire more workers to relieve some of the strain on the current workers? Just a thought.
