Is it possible to disagree with the manager's order to suspend the action...

Yes, you can. In case of disagreement of the employee with the order of the employer on the suspension of the employment contract by the employee or the trade union on behalf of the employee, the relevant order may be appealed to the central body of the executive power, which implements the state policy on issues of supervision and control of compliance with the labor legislation, or its territorial body, which , having studied the content of the order (order) and the grounds for its issuance, in agreement with the military administration, may issue an employer's order to cancel the corresponding order (order) or to eliminate the violation of labor legislation in another way, which is mandatory to be performed by the employer within 14 calendar days days from the date of receipt of such prescription.
