co-tech
A fellow technician. This coworker works with you in the same field doing the same job. Often found in areas such as computers, electronics, manufacturing, service and repair.
I'll need to ask a co-tech to finish this job since I need to leave early.
A couple of my co-techs called in sick today. My workload for today just doubled.
