Final answer:
Role overload refers to the excessive demands and expectations of a role leading to stress, unlike role conflict or role strain. Examples include working parents balancing career, family, and volunteering.
Step-by-step explanation:
The condition where individuals may simply receive too many role-related messages is referred to as role overload. This occurs when the expectations and demands associated with a role are too extensive for an individual to manage, leading to stress and potential inability to fulfill all obligations associated with the role efficiently. This is different from role conflict, which arises when there are contradictory demands between two or more roles, and role strain, which is the stress experienced within a single role when too much is required. An example of role overload would be a working parent who also volunteers and has additional family responsibilities.
