1. A work machine including a front work device, the work machine comprising:
a state amount sensor that senses a state amount relating to an action state of the front work device; and
a controller that controls the action of the work machine on a basis of an operation signal transmitted from a remote operation device by radio communication,
wherein the state amount sensor includes a posture sensor that senses posture information that is information relating to a posture of the work machine and a load sensor that senses load information that is information relating to a load on the front work device of the work machine, and
the controller is configured to assess a communication status of the radio communication, and, when restricting the action of the work machine according to a result of the assessment, restrict the action of the work machine according to one with a smaller absolute value of deceleration acceleration according to the posture information and deceleration acceleration according to the load information.
