average handle time (AHT) Average handle time (AHT) is a call center metric for the average duration of one transaction, typically measured from the customer's initiation of the call and including any hold time, talk time and related tasks that follow the transaction. AHT is a prime factor when deciding call center staffing levels.
There are four castes in Hindu religion arranged in a hierarchy. The highest caste is Brahman, and they are the priest caste of Hinduism. After them are the Kshatria, who are the warrior castes. After them are the Vaishya caste , who are business people.
Members of the Sudras caste often worked on the farms of the people of higher castes. Many Brahmin priests believed contact with lower castes would contaminate their souls. Vedic prayers were considered so pure that they could not be recited or even heard by a person of a lower caste. One Indian law stated that if a Sudras was caught listening to the Vedas, molten lead was to be poured into his ears.
