Present Perfect Continuous Tense:
The present perfect continuous tense is used to describe an action that started in the past, is still happening in the present, and may continue into the future. It is formed using the auxiliary verb "has/have been" + the present participle form of the verb (-ing).

1. My dad: This indicates the subject of the sentence, referring to someone's father.
2. has been working: This is the present perfect continuous tense form of the verb "work." Here's how each part contributes to the meaning:
- has: This is the third-person singular form of the auxiliary verb "have" used with the subject "dad."
- been: This is the past participle form of the auxiliary verb "be." It indicates that the action has been ongoing.
- working: This is the present participle form of the verb "work." It indicates the continuous action of working.
