>Can you explain more how paying double for a contractor for tax reasons saves the company money?
This may vary due to region. For example in the U.S where you can fire people quickly the contractor benefit is less apparent, but in EU where after a short period you may have to spend a long time to fire someone it may be beneficial to hire a contractor rather than going through a lengthy hiring process only to find out you want to fire them.
Contractors in such an environment often are a reasonable investment for a project that has a particular dedicated timeline. Like we expect 1 year for project to finish. We hire for 1 year, and opportunity to extend for 3 months 2 times in case it goes bad.
Otherwise you have to hire for project and then do these layoffs everybody here is complaining about.
Furthermore in EU if you are paying 10000 for an employee, you probably have extra fees on top of that so you are paying 14000 (estimation) then for contractor you are not paying 28000, but 20000. The pricing is not great, but there are lots of factors that can make it seem more attractive than it might appear on its face.
Finally, Contractors tend not to do any of this quiet quitting or whatever, probably because for them it is more a business and they are also earning significantly more that makes it an interesting business to be in and to maintain.
