A network technician’s workplace is a mix of office spaces and hands-on technical areas like server rooms. In the office, they use computers and special software to monitor and fix network issues remotely. Server rooms are climate-controlled spaces with racks of equipment like routers, switches, and cables, where technicians work directly with hardware.

Their job can take them to many locations, including offices, stores, factories, or even outdoor sites when setting up larger networks. Sometimes, the work is physically demanding, requiring them to climb ladders, squeeze into small spaces like wiring closets, or lift heavy equipment while running cables and setting up devices.

Many network technicians work in shifts, especially for companies that need round-the-clock network support, like data centers or telecom providers. They may also be on call to fix urgent problems outside regular hours, which can lead to unpredictable schedules. The job can be high-pressure, particularly when a network is down and affecting businesses or customers.
