I can send you ours if you like. Different industry but may give you some ideas?

Hi Eddy I think you would also need to take legal advise because if you test mid way through shifts your drivers have already commited offences, also if they are sleeping in cabs with keys they may well be drunk in charge of a vehicle (although I have often wondered how this works for camper vans?) Also by sending them home you would have to ensure they dont drive.

To prove drunk in charge the prosecution have to show intent to drive. There is precedent for this.

I introduced a policy to one major company and set first action level at the European level and then the UK level. for BAC and the SAMSHA levels for Drugs. The action levels were set for 'Safety Critical Workers' which I defined with HR... The process, very briefly, was if identified the employee would enter into a program with Occupational health which would assist him/her to treat the issue (either drink or drugs). Three stikes or monitoring failures then it was no longer a OH issue it became diciplinary, up to and including dismissal. Training of supervisor and line managers in the recognition is important for this to work. I did not introduce random testing, however we did put in 'for cause' either on line manager/ supervisor observations or post accident/ incident. Should also say that it started with the initial risk assessment. There are pretty good monitors out there now both for roadside drugs and alcohol...however be sure to pay the money out for the right ones... Pre-employment drug and alcohol screening should not be forgotten either in all of this. (During implmentation of this policy was pushed to start someone without it stuck to my guns and guess what he died of a massive overdose 1 week before the test...!!) The legal aspects I will cover later...(need to get on with the day job) it doesn't breach human rights if you do it properly with proper consultation, yes whatever you identify could be evidence for a formal prosecution (One manager advise the police and they sat outside the depot gate - poor managment if you ask me but hey...) Hope some of this helps... Cheers Steve
