Never burn your bridges.Leave on good terms, because when work is quiet elsewhere, you may want to go back.
Ken.
Wot he said. Bear in mind also that agency office staff move around too, and talk to each other; and drivers who mess them around soon acquire a reputation for it.

Like I said mate, I aint an agency fan, you obviously are.<<
No actually I’m not mate but if I find one that treats me fair which I did, then I’ll treat them the same. Out of all of them in this town I only found the one though. A lot of them I didn’t even get past their pathetic exam question phase due to their attitudes so I walked out before it even got that far. There are a lot of unscrupulous agencies out there who treat people badly and they deserve to get the comeuppance but like I said to the OP if they’ve treated him fair then keep them sweet… and that just applies to that one agency, not all cos he’ll never know when or if he’ll need them again.
OK, so why are we arguing?
Looking at each other’s posts it looks like we are both saying more or less the same thing.
Get outta here. We ain’t arguing, we’re debating!

Thanks again for the advice. I feel like if Fridays assessment goes well and I ring them on Saturday, i’ll ask them if they want me to do a weeks notice. They’re not a bunch of cowboys, they’ve actually been fine which I was surprised to find as I was expecting a much worse experience from an agency.
If you do go, don’t forget your holiday pay.
I was with a agency from July last year until January this year. I had been on long term work really but they treated me good. When it went quiet in January I gave my weeks notice to head off travelling! Said in leaving in a week if you get really stuck with anything give me a call but I’m happy to have the week off! They called a few times asking if I wanted work but was fine in the fact I didn’t! How ever I made sure I left on good terms and can always go back! Not worth burning bridges with somewhere that treated you good as it might take a long time to find somewhere who treats you like that again!!!

This is sound advice, I would take heed…
Just do what most drivers do leave in a second don’t give notice then come on here slating them 
but as others have said if they have been fine with you then at least tell them if they can cover the work etc. a good agency will wish you the best and tell you to keep in touch if its not what it seems.
I have a driver coming back from a perm job that didn’t work out next week he was fine with me so am fine with him.
