Because of an imbalance of power between employees and supervisors (employees' financial situation depends on whether they will have a job the next day or not), supervisors must be extremely explicit in their requests. For example, if a supervisor sees an employee is sick, they should very explicitly say to the employee, almost in the orderly manner, that they should take a sick day. This should not leave any uncertainty on the side of the employee. Similarly, if a supervisor is asking something of an employee that is outside of their responsibilities (ideally, this should not happen), and the employee says “no”, the supervisor should recognize that it took a lot of courage for the employee to say “no”. They should also give a clear sign to the employee that the request was outside of their responsibilities and that the “no” answer does not change anything in the future relationship.
