No. Firstly, in accordance with the resolution of the CMU of January 27, 2023 No. 76, reservations can be applied to representatives of state authorities and local self-government bodies, as well as to employees:
at enterprises, institutions and organizations that have been assigned mobilization tasks (orders), in the case when it is necessary to fulfill the established mobilization tasks (orders);
at enterprises, institutions and organizations that produce goods, perform work and provide services necessary to meet the needs of the Armed Forces and other military formations;
at enterprises, institutions and organizations that are critically important for the functioning of the economy and ensuring the livelihood of the population in a special period. Moreover, only 50% of conscripts can be booked and only for a period not exceeding 6 months.
In addition, it is not logical, since the postponement is valid indefinitely and its availability can be confirmed with documents from the employer (which is much easier than booking).
