I don't think employees are investors in co-ops. They are like founders. A co-op can still get capital from investors. Can't they?
Debt financing, as mentioned, is another alternative.
Read with caution, I'm really sketchy on details.
Typically, they are; their ownership stake is usually, as I understand, purchased on credit and sold back on separation.

Well, yes, in the form of debt, and perhaps non-voting equity depending on the particular rules applicable to coops where the coop is organized.
And coop members can have direct or indirect ownership a full on worker coop normally has direct ownership and organizations like John Lewis have indirect ie shares held in trust.
And by definition the members of the coop must own the coop or own a controlling interest
