Wealth isn't tied to labor though. It is tied to ownership of assets and the value of those assets as defined by economic pressures such as supply and demand. Money (not to be confused with wealth) is an asset that is conveniently fluid, a good medium for trade, since if I have bread, you have eggs, and our friend has milk, but none of us line up perfectly for a trade with each other, we can use money as that asset exchange so all three of us can end up with the amount of eggs, milk, and bread that we decide of our own volition is the best distribution for us, competitively.

If your chickens reproduce because of the bread I provided you, your wealth in assets increases if the value of chickens and eggs don't go down at the same rate. We already traded our money and bread. If I wanted stake in your chickens, we could've came with an agreement (if you are willing to share your assets and risk), and I could then demand a share of your gain or loss. Otherwise it is theft.

Regarding employees, labor has never been tied to wealth. An employee provides a service, which is traded based on the supply and demand of that service, and money (not wealth) is the standard asset people prefer. Some people are paid in a different asset, such as share of the company or a combo of both. That is their wealth. Labor is independent if you decide to trade something else, and it is always a gamble, because values of any two different assets (including money) grow and shrink independently.
