AFAIK, social charges paid by the employer in NL are around 28%, so it's less than 3000 euros per month per staff member of income.
And that's before social charges paid by the employee (18%), so it's less than 2500€ of net income per staff.

I would not judge if that's high or low in NL, but that's not 4000€

So, we can move the RIPE office to another country, with less salary numbers. E.g. there are the salary numbers approximately 1500€ in Russia, including tax 13%. With social tax 30% the salary numbers are 2000€ in Moscow.

What do you think about it? Me and my colleagues, who wrote here earlier, are ready to help the community with relocation.
