Just because the name says worker co-op doesn't mean every employee has to be vested.
In the Netherlands a coop is an acutal legal structure that businesses may adopt. It will surprise you to hear that we even a big bank which is: A co-op.
The core characteristic of a co-op isn't that the workers all have shares. It's that they have members and that the members instead of the shareholders may receive payouts based on the company income.
I realize this is different than the American case of a worker co-op. Your reaction though speaks to me that you don't consider this a serious form a company might take. Whereby you ignore that some very big and wealthy companies are in fact co-ops. I assert that this is merely because the US legal systems don't facilitate co-ops, and I wonder whether that isn't a missed opportunity?
