Answer:
Situational attribution or external attribution
Explanation:
Attribution theory talks about how people try to explain the cause of a behavior or event. There two types of attribution, Situational and Dispositional Attribution.
Dispositional attribution say that a person's actions are due to their personality or disposition.
Situational attributions occurs when we blame an event or behavior on some factor relative to the situation. For example, when we blame an event on the weather, sleep, traffic or alcohol we are using situational or external attribution.
In the Question, you are blaming your Boss's Cranky behavior on the fact that he hasn't been given a raise since ten years ago. That is situational attribution.
