Short or long, on line one

Why a crew note writes its length before it names anyone, and why a crew cannot be bought from this page.

Filed by the outsourcing desk

Short is a day or a week with a close. Long is a season or a build with a rotation. The crew note names which it is before it names a trade.

A supervisor on the site signs the note. No signature, no crew.

The paper refuses an order for a crew sent to this page. The route is the signed note, not a form.
