Or more interestingly, I'd assume an independant consulting contract could be void in many legislations if it happens that their work should be reclassified as employment under some specific rules (e.g. you dictate their working hours etc.)
Basically, is the contract valid under the worker's country laws is a question you won't be able to ignore I guess ?
Depending on treaties, not having a formal business entity in a country doesn’t make you immune to their laws and taxes (not a lawyer, but it is totally possible to collect foreign debts in the US for example), if you’re publicly traded, breaking foreign laws intentionally is a BAD idea. On top of all that most companies strive to stay on the right side of the law regardless of the ability to get away with it.
Not an exact parallel, but see the saga of the Huawei exec who was arrested in Canada on behalf of the US for a business deal made by a Chinese company with Iran.
Are you probably going to get away with it? Yes, if you aren’t a very big fish. But what if you don’t.
In this day and age though, I wonder how much it actually works . For instance if one of your contractor does something completely illegal in your country and you get media backlash for it, you're in a tight position if that thing was perfectly legal on their side, and wasn't covered by the contract as you had your own country's law in mind.
I'm not sure you could push your country's law on them, nor that it would help your situation as your company is still fronting the backlash.
And even in that setup, we all remember Nike and many other apparel makers stuck with the "child worker in a factory" image basically forever. Or Apple being questionned about FoxConn's working conditions, or the environmental impact.
When it comes to PR, pushing the responsibility to the foreign contractor doesn't looks like a good working strategy IMHO.
Does "contractor" mean something different to you than it does to everyone else? This would be like me buying an iPhone and then Apple suing me for not paying proper sick leave entitlements.
I can understand where your misunderstanding comes from, thinking they’re all just businesses providing services to other businesses. But this interpretation is very naive, and the legal reality is massively more complicated than you’re making it sound. Governments really don’t like independent contractors, they’re subject to far more restrictions than ordinary businesses, and companies employing their services are usually exposed to risks that they don’t have when dealing with ordinary businesses.
The nature of the relationship, and the work you are doing determines whether your employer is a regular employer and what taxes they have to pay. In Canada, for example, certain taxes (GST) are applied to the contractor relationship based on whether the product the company sells is available within the country, and the distinction between contractor and employee is much less fuzzy than it is in the US (if you have to ask, the person is almost certainly an employee).
It gets complicated quick
