Complaint against a private enterprise

In case of refusal to pay wages or other payments, the employee should apply to the prosecutor's office with a statement about non-payment of wages and bring the guilty parties to justice. It is also possible to apply to the court with a claim for collection of owed wages and compensation for damage caused by non-payment.
