Typically this falls under 'minion' classes - distinct from 'animal companion' classes in that the goal is having more than one at any one time, and them generally being disposable.
Necromancers have the leg up on most versions because their forces grow stronger as the enemy forces die, and bodies are plentiful when DungeonFucking.
The non-dead variety typically leans towards the 'Leader' archetype, a sort of field commander or leader of some kind of warband. Anyone with a good enough persuade stat can actually get this done in many systems, and many even have rules for it (which then typically makes the storyteller hate the system just a bit more, because it's clearly broken and not intended, but there are often a surprising amount of rules for it.)
In the vein of the Employer/Boss/Capitalist, my first thought is the Overlord, per the game Overlord; you are an Evil Overlord, and your little goblin/kobold/other diminutive replacable creature that spawns out of a hole in the ground are simultaneously an extension of your will, your meat shield, your weapon, your dick, and even your literal distant hands.
I think there's even a version of this in Cyberpunk (iirc in Cyberpunk RED), somewhere in the Fixer/Businessman types, I think there's an 'I'm Sending Hired Goons Instead Of Going Myself' ability, which is fucking hilarious to me.
