Well, this is kind of an ongoing problem with an existing colleague at work.
Basically; it hasn’t reached anything like this previously.
Came into work this morning to find the yard empty. No other drivers’ vehicles there, so parked up.
Went and found the keys for the truck and did a walk around check of it. Seemed ok, so popped the ignition on, checked the lights and then fired the engine up. Seemed ok.
Returned to the car and got my gear, then popped into the drivers office and picked up the paperwork. Returned to the truck for the second time to find the engine off. 
Hmm. I was sure I’d left this running. Obviously haven’t had enough coffee this morning 
Right. Turned the key. Cranked. Nothing else Ahh. Right. Hmm. Not working.
Checked; it had 3/4 a tank of fuel. Made sure none of the emergency stops had been stuck in or were sticking at all. Nope. Engine dead, but when I popped in the PTO the hydraulics worked ok. Not totally dead.
Next step. Being rather new to these diesel things (only been driving them 4 years) I rang the engineer. It was 0530. Being Scottish he’s difficult to understand in the morning but with no clattering diesels around 
to cause problems I seemed to understand him ok. Fine.
Explained the problem. He introduced me to something called “the fuel filter”. 
Oooh, I wondered what that was for, that thingy behind the cab…
Don’t look at me like that. I’m not dense, I just haven’t bothered before. Anyway, he said to prime it. Small pump, press it.
“Ahh, should there be diesel [zb] draining out the bottom…”
That would be a no then. He said he’d come down, so we hung up and I investigated a bit further. Seems there was a drain thingy underneath it, which was loose.
Tightened it up and primed it again. Didn’t leak. That’s a start. 
Primed it a few more times then cranked the engine, after a few turns it crankily coughed into life, let out a bit of smoke and settled into an idle at 700rpm.
Right. Rang the engineer. Explained. He said that it had returned yesterday from a job at 1600 and the only person who had been in overnight (whose truck was parked next to mine when I came in) was a particular driver I’ve been having problems with.
Trundled off to job, seething and the like.
Now; having spoken to my manager any complaint I make will be “hearsay” between the two of is. I have tried to be nice to him but its not me he’s [zb] off. Almost every driver in this depot and 4 other depots I know speak poorly of this driver. Most begging us to keep him away. Those lucky enough to receive phone calls from him either ignore or “call screen”.
The last “incident” was when he seemingly trashed the back end of a unit and then called the regional manager to blame me - who was on holiday apparently. He then rang me and left me a message telling me this. Understandably it upset me, but to my direct manager the engineer was able to back me up as he had prepped this unit for that driver to take out and hadn’t seen the damage; and then the manager hadn’t had a phone call either… 
Before I hit him (he’s bigger than me, stronger and I’m allergic to pain) can someone give me some constructive assistance 
Pretty please
