For a salary of 100k, the company pays beyond 200k. Many social charges are on the company.

My salary isn't that high, but after taxes, both on me and the company, I get about 1/3 of what the company pays for me overall.

True the expatica link touches on that point, I'm not sure how much is employee paid in other countries (and it can vary depending on how the company is established)

It definitely makes sense to avoid it as much as you can (but it is a fee not unique to France)
