'All Yours' Vs. 'All is Yours' Vs. 'Everything is Yours'

Question

Common here is All yours. But I'm not sure whether or not it's practiced internationally. Which one is better? Or all are okay? Any grammatical error?

I am strictly talking about the scenario wherein using these phrases should only mean that the possessor is allowed to do anything to what is given to them. Kindly do not come up with other cases where the possibilities of using these phrases increases or brings perplexity.

One of the scenarios:

"Listen, the sales are down and in coming days, the situation will go from bad to worse. And I don't want this to happen to our company. It is for this reason, I'm appointing you as the manager of this region. You need to work harder for this."

"Okay. But then I need some structural changes. Also, the way field workers work here is not a professional way. And..."

"Ah, whatever. You are free to do anything. It's all yours."

Note: Instead of uttering the last sentence, I may do some gesture spreading my arms and say, "All yours." to avoid "It's."

Further interesting is if I am talking about some workers (say field guys) here.

"I know the issue of field workers. In interest of the company, you can treat them the way you want. They are all yours/They are yours/All they are yours/Everybody is yours"

Answer 1

The expression that sounds better to me to express decision-making in this context would be:

Ah, whatever. You are free to do anything. It's up to you.

Because that way you are telling someone you want him/her to decide about something, which would be the same as: "The decision is yours". For me this is the big difference compared with the "* all yours" expressions which don't necessary imply decision making.

Usually "(*) All yours" is used to express the availability of someone or something in an informal way:

A: Can I borrow that book?
B: Sure, it's all yours.

A: I'd really need your help this afternoon if you're free.
B: I've got a meeting at 2, but after that I'm all yours.

Or to tell that something now belongs to someone:

The course requires you to pay the fee only one time and after that it is all yours.

In your last example, it seems right to use "They're all yours" (at least for me, the other options don't sound natural) because the workers could be treated "as someone wants", that could be interpreted as them losing some of their rights as humans and "taking them as objects". I've found a similar use in this book, but with girls instead of workers.

Extra (related with some previous comments on the question): "It's all in your hands" is more like "it's down to you". These expressions are used when for some reason you're the only one who could take that task at that moment. See this

Answer 2

"It's all yours" is what you say when handing over responsibility.

Pilot, leaving flight deck of a 737 to co-pilot,

"It's all yours."

Conference host, handing over the lectern to a guest speaker,

"They're all yours."

-And that's pretty much the context for the phrase, "it's all yours."

"I am strictly talking about the scenario wherein using these phrases should only mean that the possessor is allowed to do anything to what is given to them."

I would feel very uncomfortable about saying "It's all yours" in order to convey that meaning.

I might say, rather' "The choice is yours."

Answer 3

More colloquial would be:

"It's all in your hands"

or

"You have carte blanche to do you you feel best."

Strangely, you can use the French phrase in colloquial English!

Answer 4

'All Yours' Vs. 'All is Yours' Vs. 'Everything is Yours'

All yours is by far the most standard of the three, especially with the hand gesture you've mentioned. It also does hold up internationally. The other two are decidedly formal and uncommon, and all is yours strikes me as archaic sounding. All of them are grammatically correct and essentially semantically equivalent, however.

If I were to nitpick semantics, I'd call out everything is yours as slightly different from all [is] yours. All might mean everything, or it might mean entirely; thus all yours could convey this one particular thing is entirely yours but everything is yours cannot carry that meaning. In colloquial conversation this is a non-issue as people will generally understand your intent.

"I know the issue of field workers. In interest of the company, you can treat them the way you want. They are all yours/They are yours/All they are yours/Everybody is yours"

• They're all yours - this would be my choice, and I would definitely use the contracted form. This is already an informal response, and the contraction flows better while also de-emphasizing the possession. This is the idiomatic and natural thing to say.
• They are yours - to me, this conveys the sense of possession too strongly. You don't own the workers (I assume they're not slaves); you're free to manage them as you see fit.
• All they are yours - this is ungrammatical. You can amend it to all of them are yours, but this has an even more pronounced version of the second phrase's problem.
• Everybody is yours - once again this sounds too literally possessive.

I'd also like to agree with the remarks in the question's comments. These phrases are used to express you're in control, which does not necessarily mean you may do anything you want. Given that subtle difference and this statement:

I am strictly talking about the scenario wherein using these phrases should only mean that the possessor is allowed to do anything to what is given to them.

I am forced to say that you shouldn't use any of these, because you strictly want to say that the recipient may do whatsoever they wish. For this sense, I suggest one of the following (in descending order of preference):

• Do whatever you want
• Everything is entirely up to you
• You own all of it
