So many of the recent layoffs have not accounted for individual performance or criticality to the business

And you think a union will?

Unions make more sense when the workers actually are interchangeable. Are you?

It doesn't matter, if my employer would treat me as interchangeable anyway.

And even interchangeable employees deserve reasonable accommodations. I do think a union can highlight those needs more effectively than individuals (especially for interchangeable ones, to your point).
