Dilemma dilemma :(

:agree with both of you ^^^^

Should mention that only extra money I'll get is is about £5 a day for the driver training role, the safety rep one is basically through the union but we're all salaried so our guys aren't interested in the money/overtime scenarios.
I applied for the driver trainer role a couple of years ago but again the union rep got it, I personally think it was done that way to get him out his union role and they've now succeeded with giving him the transport manager job.

I'll phone the guy tomorrow that took the interview for that job and ask him about it, ie if it's up for grabs, do i need to reapply gain etc.

All I can say is what I say to my kids who talk about taking on extra roles/responsibility but only for very little extra money is that although its for little extra pay it will be worth a lot more on your CV in the future.
You clearly want to go for it. In situations like this I always think "what would Rick Say "
