Pros
Not much I can think of lately.
Cons
High Stress environment (watch colleagues go from happy/bubbly to a shell of their former selves within months). Impossible workload. Constantly changing processes. Unattainable bonus system (yet they still increase the tasks per visit but expect more jobs done). Micromanaged beyond imagination (including camera footage review team). Expected to do basically 3 or 4 jobs in one and chastised for the smallesr error (for example missing a question to their neighbour about how old their kids are or not putting a blue zip tie on an already blue cable). Safety issues with Lone Working in this role are ignored by management despite verbal and physical threats, baseball bats, knives, cannabis grows etc. Field Reps and FDS Engineers who didn't jump ship at the VR stage are wishing they had.
