I don't blame the company
Those that work there know how the company plays the game. They have an established method of operatiing. Hey a bear is a bear don't mess with it. The guy who ratted him out is another issue.
All that said the company has been known to employ private investigators to do their bidding in which case, they throw away more good will.
Again that said the company is playing hard ball and the union had better not bring it weak.
