"Employee of contractor or sub-contractor" Difference ?

[Airerdem]

Hi everybody anybody can declare the differences ?

1-) Employee of contractor or sub-contractor.
2-) Employee of contractor, or sub-contractor.
3-) Employee of contractor and sub-contractor.
4-) Employee of contractor, and sub-contractor.

Employee of contractor is constant. But which sentences say Employee of sub-contractor and which sentences say only sub-contractor as a firm not individuals ?

Thanks in advance

Can you explain your question a little more? It's possible that a lot more context would be required.

By default I would understand them like this:

1-) Employee of [contractor or sub-contractor].
2-) [Employee of contractor], or sub-contractor.
3-) Employee of [contractor and sub-contractor]. -- but seems unlikely in practice that someone would be an employee of both
4-) [Employee of contractor], and sub-contractor.

However, unless there is some firm legal convention that I'm unaware of, I would not want to rely on these interpretations for anything important. To avoid possibility of ambiguity they should be rephrased.

First of all thanks for your posts.

Beeesneees and Dozy there is a clause in contract that says

"If owner ascertains that an employee of contractor or sub-contractor misbehaves or is inefficient in regard to his qualifications, contractor shall immediately evict such person from site if required by owner."

The owner evicted the sub-contractor from site. But the contractor says this clause relates to individuals and not entire companies.

So,

If the meaning is [Employee of contractor] or sub-contractor. Owner is right.
and
If the meaning is Employee of [contractor or sub-contractor]. Contractor is right.

I just put other possibilities to previous post to learn them ;)

[Dozy]

If there was ever any doubt, in this case the later reference to "such person" seems to clinch it -- it surely must mean "Employee of [contractor or sub-contractor]"? (Again I emphasise that I am not a lawyer and you should not rely on my advice if this is a real-life dispute.)

Yes it is real life contract and we are examining it in very detail. Every "," has a meaning in law that is why I'm asking to be sure and your ideas are just directing me do not hesitate to reply ;) Thank you very much.
