I worked with a bloke once for 2 years and he would backstab workers and roadblock jobs he never had any part in with health & safety issues. I turned a blind eye to it a fair bit as did the managers of the company for a while. Within reason, we needed to get the job done without worker conflicts and these blokes weren't amateurs, most of them had 20+ years of onsite experience, so they had a fair idea of what would really be fatal.
Jumping from job site to job site you soon realise how political and contradictive this all gets because safety protocols vary like chalk and cheese, competing companies and individual workers soon weaponise this against companies and individuals for their own personal gain to remove them from site to either take their work or job position. Anyway, back to this bloke I worked with, I always suspected him to be a bit of cock in the back of my mind, always bringing up trivial shit in toolbox meetings, things that had nothing to do with him, and half the time you'd catch him out doing the same wrong but the last job I was on with him just proved how two-faced he was.
Due to more worksite politics with authorising vehicles to enter sites, no one in this contracting company was allowed to drive their personal vehicle to the work sites, this became company policy for many reasons, most people were fly in and fly out workers in any case. This bloke goes behind the contracting company's back and gets his vehicle authorised to enter the site from the site manager and decides to drive into work. On the way to work he picks up another local worker, then the coppers in another town manage to pull him over for speeding, then book him for bald tyres and then realise he has no license to start with and has a 2 year driving suspension for driving under the influence. This was the same person reporting everyone for minor safety issues just about every day.
