NigelB makes some very good points, for example about solicitors pursuing legitimate claims regarding cases of work-related injury, death and disease. As most such cases receive no publicity, the vast majority of people in the UK have no idea about what they involve. By contrast, a few compensation cases - with interesting circumstances or high newsworthy payouts receive considerable or even disproportionate media attention, and thus perpetuate a skewed impression about the compensation system.
In addition, though most of us as forum users have a clear idea about the nature and roles of HSE, OS&H advisers, employers, insurers, police, etc, they can be a notable or complete mystery to many other people.
For example, before interviewing an injured person in the course of investigations during my time with HSE, I usually had to explain what HSE was and that inspectors weren't acting on behalf of the person's employer or the employer's insurer. Also, I would explain the statement procedure and that the ensuing statement would not be given to the person's employer. Taking appropriate time and care with such explanations to put understandably anxious interviewees at ease almost certainly helped to make the interview/statement taking process more effective for me and the interviewees.
At the end of such interviews, sometimes with badly injured persons who were in hospital and likely to be there for weeks or even months, I tended to ask the interviewees if they would be getting/seeking advice, say from a trade union or a solicitor if they weren't in a union. Either way, I would advise that if they wanted a copy of the statement I had taken, I could add the words "I wish to be provided with a copy of this statement" before they signed my handwritten copy. After the statement was typed, it was no problem to send a photocopy to the person who knew they could share it with a union rep or a solicitor. I can't recall how this practice evolved - perhaps it was gleaned from one or more experienced colleagues. Also, though it wasn't part of HSE procedure, my bosses must have known about it from reading the statements. Also senior bosses would have known from reading through and approving prosecution reports, but neither they nor my bosses ever complained. Anyhow, I hope the practice was of some help, especially in the case of persons who were not especially articulate and/or where the machinery or work systems involved were quite technical and not easy to explain to solicitors and others not familiar with them.
