Blood, Sweat and Broken China (the Removals thread)

Just flicked through a couple of pages, so please forgive my questions. I created a thread earlier about me, a bus man, converting to the other side- HGV driving.
Seem a few companies looking for bodies- Porters and drivers. Any idea what a hgv driver is typically on?
Is it fairly steady and secure? What if the house movers scene dried up, presumably the company won’t pay you? Is the HGV class 1 or 2 generally?
