Well, it is the labor union representing the workers stating it. It's clear in the article and from the context.

Omitting that from the title doesn't really detract from message. I get what you're saying, but it's not propaganda, and the NWS isn't even saying they aren't understaffed (with the quote you offered as proof that they disagreed).

They are saying they aren't putting their staff in dangerous situations, which is clearly being disputed by the staff and their union. They aren't saying being understaffed is fine.
