Tech: "I was looking something up."
Supervisor: "Ok, you need to take some extra time then to do your work. That's ok. Steve doesn't need to take so much time to look up things. When your knowledge grows to the point you don't need to spend so much time looking things up, we can start raising you pay closer to what Steve makes. Or, if you really need to look up a lot of stuff, maybe a lower paying apprenticeship position might be more appropriate for you."
