Translated: Management ("wasn't represented due to job classification") doesn't like unions. Shocker.

I know plenty of line level engineers (mostly non-software) who's main interaction with unions is things like waiting for a week to move their desk to the other wall of their cubical because that's a union job and they're not allowed to touch the Ethernet cables.

Notice the story has cubicals, how nice! Most these stories are pretty old. I suspect because there are less jobs in some big F500 campus with colocated engineering, accounting, etc and a unionized manufacturing plant all in the same place.
