I am trying to put together a company policy on working hours. I have a large number of field based operatives who work a core 40 hour week. They may then may undertake planned overtime or be called out for emergency work. Call outs may involve travel time of up to 2 hours each way. I need a policy that will not only satisfy the regulations but will provide a ethical and safe solution. Has anyone faced a similar situation? Any advice or help would be appreciated.
