Because we in britain don't make anything useful anymore we can only manufacture jobs. In this process someone is given a meaningless and never before seen occupation that they then have to justify. If they can build a workload sufficiently onerous they can then ask for help, making themselves head of a department. They can then create more non-work and promote themselves to manager. Soon Britain will be employing everyone to screw up the lives of everyone else. Everyone will become a manager and everyone will be policing some aspect of everyone else's lives. Health and safety is but one of the manifestations of this idiocy.
