If i create an organizational account for my nonprofit using its shared email address, how will access work?

Hi ​@Heath_IL, welcome to Zoom Community! Since you’re looking at a Zoom Workplace Pro subscription, even if 10 people know the login, a single Pro license can only host one active meeting at a time. You can schedule as a many meetings as you want for different times, but they cannot overlap. Anyone with your shared email address can sign in to the Zoom desktop app or web portal. Zoom allows you to be signed in on up to 2 desktop computers, 2 tablets, and 2 mobile devices simultaneously. If a third person logs in on a computer, the first person will be automatically signed out. 

Any staff member can log in, schedule a meeting, and send the meeting invite to participants. To start the meeting, the person must log in as admin@ournonprofit.org. Once the meeting is live, they can assign a participant as a co-host. This allows the ‘admin’ to leave the meeting while the other person continues to lead it. 

If you find your team often double-books time slots, you may want to use the discount to purchase at least 2 Pro licenses instead of 1. This would allow 2 separate people to host meetings simultaneously under the same organization. I hope this helps.
