Pros
Opportunity to work on a wide variety of equipment. Standards are kept up to date and continually adding new equipment to their inventory.
Cons
Can be long hours, 14-15 hr days at times. Poor Quality Assurance, Datasheets have wrong specs listed, some technicians just fill in numbers and datasheets without taking readings. Management will praise you one day for work you have done, then the next day written up for failing to meet employee performance goals. Technicians can take shortcuts on procedures, not acceptable at good calibration labs. Shop managers would talk to other employees about how they have written up other employees, this should remain private. At some locations, walking through the lab, some of the technicians have pictures of scantily clad women on their computers as background. Makes a real good impression on customers and inspectors, some of whom are women.
