Honestly, what does this mean? If you abolish ownership, then working "for" someone changes in meaning.
Once ownership and profit are gone, working "for" someone stops meaning "for their economic interest" and starts meaning something very ambiguous. Don't carry over the emotional meaning from one mode of production to the other.
You might mean working according to someone else's plan. Is that working "for" someone? Maybe you mean working with someone who has the power to bar you from participating in the work or has the power to stop you doing certain actions?
It's not clear what you mean, so it would be helpful if you clarified.
