A regular employee can be disciplined for which of the following?

Disciplinary actions in a workplace typically involve a range of behaviors that violate company policies or expectations. Insubordination is a clear violation of the expected behavior for an employee, as it relates to refusing to obey lawful orders or directives from supervisors or management. This type of behavior undermines the authority of the supervisory staff and can disrupt the functioning of the workplace.

When employees are insubordinate, it reflects a disregard for the structure and hierarchy that is essential for maintaining order and effectiveness within an organization. Therefore, consequences for insubordination are warranted to ensure compliance and preserve the integrity of the workplace.

Possessing illegal software, while serious, may not directly relate to insubordination in the context of immediate disciplinary actions unless it's been specifically addressed by company policy. Changing jobs is generally a personal choice and not grounds for disciplinary action unless it violates a contractual agreement. Not participating in exercises may have implications, but it typically wouldn't rise to the same level of severity as insubordination regarding immediate disciplinary measures. Thus, insubordination stands out as a clear and actionable basis for discipline in workplace environments.
