Law of Ukraine on the Organization of Labor Relations under Martial Law: Key Amendments

On November 3, 2025, the Law of Ukraine "On Amendments to Certain Laws of Ukraine Regarding the Organization of Labor Relations under Martial Law" (hereinafter referred to as the "Law") was published in the official newspaper "Holos Ukrainy". Most of the amendments will enter into force on December 4, 2025.

The Law introduces a series of amendments to regulatory legal acts (including the Law of Ukraine "On Mobilization Training and Mobilization" and the Law of Ukraine "On the Organization of Labor Relations under Martial Law") concerning the specifics of military service deferment (booking) for conscripts, probation periods, and the grounds for termination of employment in cases of non-compliance with military registration requirements.

Military Service Deferment (Booking) for Conscripts

Upon the Law's entry into force, deferment shall apply to conscripted employees (military liable persons) who:

• Lack military registration documents or have them improperly issued;
• Are not on military register (i.e., failed to register for military service);
• Have failed to update their personal data;
• Are wanted for violating military registration rules, defense legislation, mobilization preparation, or mobilization.

The duration of the deferment for such employees shall not exceed 45 calendar days from the date the employment contract is concluded. Furthermore, this type of deferment shall be granted no more than once per year.

If the conscript rectifies the military registration violation within the 45-day period, they may be booked (granted deferment) under general provisions. However, this deferment does not exempt such employees from liability for violating military registration and mobilization legislation.

Probation Period and Termination of Employment

When concluding an employment contract with conscripted employees at critically important enterprises, the probation period upon hiring shall not exceed 45 calendar days.

Furthermore, the employer shall have the right to dismiss the employee if the employee fails to bring their military registration documents into compliance with legislative requirements.
