i’ve been back to 2 ex employers, grampian maclennans of aberdeen and gerry jones transport of cwmcarn, and i would go back to both again in a heartbeat. and if truth be known i would go back to van den bosch tomorrow if it wasn’t 3 weeks away from home 
I have done it three times, twice it worked out better than the first time, once it was a total failure, although it was a personality clash and a wish to be home a little more that finished it.
I have been back to 4 previous employers,have always left on good terms and I reckon i could go back to most of them again if I wanted to.
Cheers for the replies.The main reason i left was for more money but the firm i went to painted a very rosy pic.Not so wet behind the ears now just itching to get back into it.Only 2 weeks to wait now.
