In 2004 the trade magazine Voice&Data described a basic fact of the call center business. Because of the time difference with the United States, “international call centers have to operate at night in India.” Staffing follows the calling patterns of American customers. The night shift brings its own costs, such as late-night transport, cafeterias and higher staff turnover.
In 2022 Telangana Today reported that major IT companies in Hyderabad pay a night shift allowance of 300 to 400 rupees a night.
