I looked at the job posting again on Channel Zero's website, chz.com for CHCH, to see if this is really an anchor position.
Another line at the end of the post says:
"Union position is nominally"
Looking up nominally online: in name only; officially though perhaps not in reality.
Another definition reads:
Something nominally true is true in name only. This refers to things that are only titles or formalities. It's the opposite of "really." Words with the root nom relate to names, and nominally refers to situations where someone has a name or title that doesn't carry a lot of weight.
Based on this, it's mainly a reporter position with opportunities to fill in as an anchor.
