Cable subcontractors are hired by general contractors to install and repair cable television, internet, and telephone systems in their construction projects. In this role, you are an independent contractor who works on a short- or long-term basis on specific projects. You install and set up cable equipment, troubleshoot problems, and perform upgrades when necessary. When you are hired for a job, you travel to the worksite and complete the installation or repair by the designated deadline. Cable companies may also hire you to help with staffing shortages and assign you to install or repair cable systems at customer's homes or offices.
