Hats off and total respect to you OP.
I used to work with a law firm that was home to one of the country's most feared criminal solicitors, coroner's office and handled NHS medical negligence cases and prosecutions brought by Health and Safety Executive.
Lot of people tend to wrongly assume when you're fighting cases and taking down NHS or on the side of Health and Safety you are somehow soulless, money grabbing ambulance chasing types devoid of anything more than a black heart.
When you do see the people behind these cases, hear their gutwrenching stories and how they were failed, it's a different world and such a rewarding job to help them get justice and have someone admit their fault and accept liability.
I work with and for CQC occasionally when they need a more indepth, specialist inspection focusing on records, notes and all care related documents. NHS sadly remain the worst for poor record keeping, fiddling, altering and either writing up the most vague entries possible or making it up, adding bits on and not even bothering to make sure it checks out with other records.
Can't change what happened or give back what someone has lost but it makes sure there's less chance of it happening again and whoever royally fucked up and left them that way is held to task.
For me personally working with HSE was the most rewarding because they are the most fair, decent and helpful people who will give employers, businesses and individuals all the help they need to do what they should and be above board and keeping people safe.
When someone repeatedly tries to skip out, cut corners and has a history of non compliance and HSE decide enough is enough, holy shit do they come down on them.
