That is why Deloitte, PwC, Tata, ... and the list goes on, exists. They were the gig economy before the likes of uber, door dash...

I worked for a multinational a long time ago and learned 2 important things:

• Some countries have strong labour laws, and a judiciary that bites. The company was sued and had to compensate those contractors similar to employees, including severance packages for people that were dismissed.
• One of the main unions (some unions cover a sector of the industry in a country rather than a single company) brought up terms related to contractors, to ensure they would have similar benefits, and they manage to get a few in during the collective agreement, sadly it only affected people in that region. It was ridiculous, some RH firms were paying people 10% of what they were billing us. It was cheaper to hire them straight, but for silly reasons we were not allowed to.
