We're getting so detailed that I'll mention the following applying specifically to Finland. It's possible to have temporary/fixed-time contracts too, and lots of people do. It's however illegal for the employer to chain temporary contracts one after another instead of offering a permanent contract if there's a continuous need. If this happens, the employee may sue on grounds of it being de facto permanent employment. If successful, they will get all the associated benefits, including things such as compensation for wrongful contract termination and withheld bonus payments only available for permanent employees. Suing is pretty easy/risk-free if the wronged person is in an union, and the unionization of workforce is around 60%-70%.
