When full-time you don't have set hours. You arrive before 8 AM to load up your van with your glass for the days work and you aren't done until you finish all your jobs. At any point throughout the day more jobs will be added to your route. This means that you need to not only complete the jobs given to you in the morning, but also return back to the shop to pick up the new glass and attempt to keep these new customers satisfied.
Safelite has expectations for each job you do. The technician must complete the job in a timely manner (120 mins), vacuum each car, wash ALL the outside windows, and inform the customer about the online survey they can take. It is a bit much to complete within a small period of time when you have many more jobs to go to next.
Most customers will give you a hard time due to many factors. The price of the job is too much, you took too long to install the new part, or you did not arrive when you said you would.Its no easy task keeping all of your customers happy when you are given an absurd amount of jobs to complete. Most technicians learn to start cutting corners on each job to get things done.
