i nearly got thrown off site months ago for my rigger boots. Aparently your not allowed them anymore, but fuck knows why. they're the safest for my job (wagon driver) no laces to trip on climbing the steps to the cab and in and out of the back of the wagon etc your 10 ish feet in the air so not a good place to trip.
New rules meant they weren't allowed anyhow and he was going to report me until i told him to fuck off and let me work. he took down my registration, name, then got red faced when i told him the company name lol, its my wagon.

cross hired wagons have diplomatic immunity on some things.
