🔹 Introduction

 The Labor Code not only protects the employee but also clearly defines his duties towards the employer. Failure to fulfill these obligations may result in disciplinary penalties and, in more serious cases, termination of the employment contract, even in a disciplinary manner.
 

🔸 1. Legal Basis

• Labor Code, art. 100–104
• Art. 52–55 LC – sanctions for violation of duties
• Regulation on general safety rules

🔸 2. Basic Employee Duties (art. 100 §1 LC)

Every employee is obliged to:

1. Perform work diligently and carefully,
2. Observe working hours and discipline,
3. Follow the orders of superiors, unless they are contrary to the law or the contract,
4. Comply with health and safety and fire protection regulations,
5. Care for the well-being of the workplace, protect its property, and maintain confidentiality,
6. Observe the principles of social coexistence in the workplace (e.g., respect for colleagues, communication culture).

🔸 3. Detailed Duties (art. 100 §2 LC)

 The employee should also:

• adhere to the work regulations,
• comply with anti-discrimination and anti-mobbing policies,
• take care of entrusted equipment and tools,
• not engage in competitive activities without permission,
• report hazards in the workplace.

📌 Note: In the case of remote work, the employee must also adhere to these principles – e.g., maintain data security and observe work time discipline.
 

🔸 4. Respect for Work Organization

 The employee should:

• arrive on time,
• follow schedules and timetables,
• not leave the workplace without permission,
• report absence or lateness immediately (e.g., due to illness or emergencies).

🔸 5. Information Obligation

 The employee is obliged to:

• update personal data necessary for payroll purposes,
• report changes (e.g., address, surname, bank account number),
• provide certificates (e.g., for sickness, paternity leave).

🔸 6. Confidentiality and Loyalty to the Employer

 During employment (and sometimes even after its termination – if a relevant clause is signed), the employee:

• must not disclose confidential information,
• should maintain trade secrets,
• must not act against the company's interests – even outside working hours (e.g., online harassment, defaming clients).

🔸 7. Consequences of Violating Duties

Lateness, unauthorized leaving work - Disciplinary penalty (warning, reprimand)
Non-compliance with orders - Termination of the contract with notice
Serious violations (theft, sabotage, alcohol) - Immediate dismissal (art. 52 LC)
Disclosure of trade secrets - Material or criminal liability

📌 The employee may also be financially responsible for damages caused by intent or gross negligence.
