Geminis need to be able to talk as often and as freely as they want to. Probably the best job in the world for Gemini would be a gossip columnist!
A Gemini would rather supervise than do the grafting, thus they are usually at the top of their professions. Gemini bosses can charm their staff into working overtime without pay.
If charm doesn't work, they manage to elicit sympathy instead. They want all their staff to think them indispensable – however, staff don't necessarily play along! And the typical Gemini flirts as if there's no tomorrow.
