The study deals with organizational and legal principles of supervision and control over compliance with labor law in Ukraine during martial law. There were determined general trends in the development of labor law and peculiarities for the organizational and legal supervision and control provision in the field of labor. First, it is a legislative narrowing of labor rights and at the same time preservation of such a guarantee of compliance with minimum labor rights as supervision and control. In the conditions of martial law, state supervision (control) measures are carried out in a more favorable mode for employers: conducting only unplanned inspections, a limited list of reasons for conducting inspections, and non-application of fines provided that the orders of labor inspectors are fulfilled. Second, the trend of increasing the flexibility of labor relations corresponds to the strengthening of supervision (control) over undeclared work, which is accompanied by the broad application of informational and advisory measures. Third, the general trend of modernization of the national system of managing the safety of workers at work based on the principles of proactivity and prevention of industrial risks corresponds to increasing the role of the employer's internal control in ensuring proper, safe, and dignified working conditions. Finally, the digitalization of supervision (control) measures is one of the optimization trends and the general direction of improvement of public administration.
