Because our contractors provide us a 1-6 month, non-full-time, packaged, isolated service by an agreed deadline for a lump sum, they're very far from the definition of an employee in all countries, so it's not a problem with us. However, if your company starts directing tasks, or otherwise starts creeping toward the fine line, then what happens is out of my expertise, sorry. My useless advice is to stay far from the line, but of course some businesses might not be able to easily do this.
