Tense

• Tense refers to the period during which an action is taking place. It can be divided into three periods- present, past, and future.

• The action that has been mentioned in the sentence began in the past and is completed in the present. Therefore it takes a past perfect tense.

• The past perfect form of 'work' is 'had worked.'
