Švarcsystém is an illegal scheme where an employee who actually works full-time (schedule, instructions, one workplace) is registered as self-employed with a živnosť (sole-trader licence) "on invoice". This way, the company avoids social security contributions and labor guarantees.
From 2026, such cases will be easier to prove, and fines for the employer can reach €200,000. The risk for the employee is that without an employment contract, there is no paid vacation, sick leave, severance pay, or protection upon dismissal.
