Second vote for using a personal email for your personal equipment's org, and your work email for your work org(s).
You can add your personal account as another administrator to your personal org, activate that account, then delete your work email address from that organization.
Best practice recommends using 2 admins at any given time, so I'd use two personal accounts on your personal dash. Or more. My partner knows what he's doing, so he's got full org access to the network at home.
