Posted By Bryan Owen Unless your temps had done something completely stupid ('Yes of course it's OK to play with the electrics with wet hands' stupid), the HSE would generally not pursue a case against an individual. They would focus their efforts on the company, for not ensuring that the temp was up to the standard that you are trying to bring your full-time supervisors to, and for not supervising the temp's work properly. This does not necessarily mean that all temps have to be qualified, but that they have to be competent to perform the tasks asked of them. To find this out, start by asking yourself if you would work under the temp. Do they work in a slap-dash manner, take short-cuts, ignore any working instructions, etc? In effect, can they manage the situation, or do they let the situation manage them.
