How do call centres ensure round-the-clock availability for IT support services?

Call centres ensure round-the-clock availability for IT support services by operating with 24/7 staffing and shift rotations. They have the infrastructure and personnel to cover all time zones, including nights, weekends, and holidays. Call centre agents are trained to handle IT inquiries and issues at any time, ensuring that clients or employees always have access to support. Additionally, they can implement on-call or after-hours support teams to handle urgent matters during non-business hours, further enhancing round-the-clock coverage.
