I could use the PROSA versus CSC example (which is actually the IT-workers union against a computer service company) which is going on right now. CSC is trying to get rid of 22-months notices before firing any employee, the union has given notice of strike.

But thats a Danish dispute which I doubt many here is familiar with, hence the Detroit example.

And it is hardly "one specific" example: its multiple agreements with multiple companies.

It's generally accepted that the singular of "anecdote" is "proof".
