YTK is an unemployment fund for employees. It means that only employees can join and insure their employment with us. Entrepreneurs cannot.
An entrepreneur can join an unemployment fund for entrepreneurs. There is one unemployment fund for entrepreneurs in Finland: Suomen Yrittäjäin Työttömyyskassa (SYT).
If you work both as an employee and entrepreneur, you can choose whether to insure the work done as an employee with us or the work done as an entrepreneur with an unemployment fund for entrepreneurs. You cannot be a member of two unemployment funds at the same time, however.
