The Alby extension on desktop supports multiple accounts. I do that in Firefox to switch back and forth between this account and Nostr Report. You could also use a different browser entirely for the work account, and install Alby or nos2x signing extension on it. On mobile too I run multiple client apps for different accounts, works pretty well unless I need a particular feature from one app. Some clients also offer built-in multiple account support: Amethyst, Nostur, and Nostrudel are ones I know of.
