Role demands relate to pressures placed on a person as a function of the particular role he or she plays in the organization. Role conflicts create expectations that may be hard to reconcile or satisfy. Role overload occurs when the employee is expected to take on too much. Role ambiguity means role expectations are not clearly understood and the employee is not sure what to do. Unfortunately, individuals who face high situational constraints by their roles (such as fixed work hours or demanding job responsibilities) are less able to engage in proactive coping behaviors, like taking a break, which can reduce stress levels.65 LO.1
