If an employee does not perform work without justified cause or performs it improperly, or due to other illegal or culpable action has caused losses to the employer, the employee has a duty to compensate the losses caused to the employer. 
The employee shall be liable only for the reduction of the present property of the employer, but not for reduction in expected profit.
If losses to an employer have been caused with malicious intent of the employee or due to his or her illegal, culpable action not related to performance of the contracted work, the employee shall be liable for all losses to the employer.
An employee whose work is related to an increased risk of losses shall be liable only if losses to the employer have been caused as a result of malicious intent or gross negligence.   _{Your Comment}
