The employee obligation corresponds to the legal requirement that the employer is obliged to provide conditions for maintaining and improving professional qualifications of  employees for the effective performance of their obligations under the employment relationship in accordance with the requirements of the performed work and their future professional development (Labour Code, Article 228 a). In the case of a long absence of the employee, the employer is obliged to provide him/her with conditions for acquaintance with the work and any innovations implemented during the absence and for achieving the necessary qualification level for the effective performance of work obligations.
