In Europe, you can't drive for Uber or deliver food without a standard work contract which includes: healthcare, pension, payroll and income taxes. Drivers here PAY private companies a weekly amount in order to work for Uber et all (to have that contract). Uber et all work with these companies only, not individuals.
Is healthcare in employment contracts actually standard in Europe?
In some states there's a national insurance plan, in some you have a tax-funded healthcare, and in some you have mandatory health insurance (with private insurers, based on your income, 15-30%).
