Re: A number of sound decisions?
The law regarding "Scheinselbständigkeit" is aimed at contractors who work for one client exclusively. These contractors could just as well be employees of their client, with all that entails (mainly social security stuff like health insureance, unemployment insurance and pensions, the payments of which is split between employer and employee).
That's where the 2-year-rule comes from. It's also mainly targeted at the lower end of the labour market, where companies have outsourced work to "contractors" who worked solely for them, still got their low wages, and were then supposed to pay health insurance themselves and save enough for retirement. Obviously, they would then have to live off social security when retired. The companies would have saved a lot of money, and the state would have had to pay. Hence the law.
The law does not affect "Freiberufler" who have more than one client. At our software company, we have contractors who have worked for us for over 15 years straight.
