When should an employee not use or answer their personal cell phone?

An employee should not use or answer their personal cell phone when ordered to stop by a supervisor because this directive represents the authority and operational protocol that must be followed in a professional setting. Compliance with a supervisor's order ensures that the employee remains focused on their duties and responsibilities, especially in situations where distractions could compromise safety or operational effectiveness.

In critical environments like fire scenarios or training sessions, there are additional expectations in place regarding communication devices to maintain safety and professionalism. However, the most significant reason for refraining from personal phone use in this context is the obligation to adhere to direct orders given by a supervisor, who may have a larger perspective on the team's needs and priorities.
