Cumbria biomass work questions

We’ve had all three companies working out of our yard all on the same contract,waste work, although lately its predominantly AW Jenkinson’s.

I might be wrong but i think Dent’s do a lot of Subbie work for Jenkinson’s? Stobarts use a lot of agency drivers but Jenkinson’s are full time mostly and seem happy enough.
Probably not much between them pay wise though Jenkinson’s are the bigger company walking floor wise so maybe easier to get in with?
