I got work off Manpower Warrington in 2015 for about 6 months. I didn’t do any RM shifts for them but I did a weeks cpc in their offices and the other drivers were mostly on RM, including the trainer. They were all happy enough and had no probs getting on the parity pay unlike some agencies that pull you off the job before 12 weeks. None of them got a full 5 shifts in a week though, seemed to be around 3 or 4 but the hourly rate made up for that. Oh and the cpc is free with manpower
