>in order to get compensated

That language is based on the assumption that they're not already being compensated.

Their compensation is what they agreed to accept as payment for their labor. So they're already being compensated. If they want to "own" part of the company outside of this agreement, they need to buy a piece of it. If you want that as part of your employment agreement, negotiate it beforehand, either individually, or as part of a union effort. If you can't negotiate it through those efforts, then accept the fact that the employer believes they can get a better deal on the labor.
