Working Conditions for Computer network technicians

Computer network technicians usually work 40 hours per week. If computer support is needed outside of office hours, such as when a large-scale maintenance project means that the system is down, they may work evenings, weekends or be on call. When problems come up, computer network technicians may need to work overtime. The internet has changed this career somewhat. While some computer network technicians work in offices, people in this career can also provide remote support from a home office. People who work for companies that provide services on contract may spend part of their day travelling to clients' offices. People in this job spend many hours sitting at a desk, working on a computer. This can cause eye, wrist, back or neck strain. It’s important to use a chair that allows good posture and to have a workstation setup that lowers joint pain caused by typing or using a mouse.
