I had written up a big reply and tapatalk ate it 
Heyjay - wait until you see if the company will take on board any of the OH recommendations. They have no legal requirements to unfortunately. They can deem any part of them "unreasonable" for the business and then send you down the official grievance and tribunal routes
I know you don't trust your union too much either, but I would try to get them on your side as you may need their help. I'm sorry HR/managers are being so difficult 
JFK - for the lung charity, they may have run out of funding for IT and lost whichever volunteers managed social media. I would get to know the group and their leadership before making any decisions on helping. I learned the hard way that the management can make or break what it's like to volunteer for something!
My five....
1. Car passed its first MOT since we bought it with no issues. *phew*
2. Officially out of money. Need to quickly find a way to earn enough to cover car insurance and US bills. Probably going to go the route of selling crafts and continuing to file a self assessment at least until my hands give out. My TOR 12 months have passed so at least I can do that without having to buy new materials. Thank goodness you don't need to sign up for VAT until you're doing a much bigger volume than I will.
3. I started a seed tray a little over a week ago and have my first little sprouts! I don't have a heated propagator so some will take a lil longer, but that makes me happy.
4. My husband was sad that his barclays thing to validate transfers had died. Thankfully I brought a multi screwdriver set from the US and saved the day and replaced batteries.
5. Signed up for a 6 week course for people with chronic illnesses that the local council sponsor. You can become a patient advocate or peer support after going through it, and it covers some useful topics so I'm looking forward to it. And our local game space is starting a kids club, and they asked if I could help with that so I'll be meeting with them soon.

Congrats on your sprouts! I always say I have a black thumb, rather than a green thumb. I have somehow managed to kill Jake, my cactus, this year. -sigh-
Thank you for the advice regarding OH. I will wait and see what they say, but only as a means of biding my time until I can find alternative employment. I do not trust my managers anymore, and I will not give them any more of my time than I absolutely have to.
Thankfully, I have been exchanging some very promising correspondence with a recruiter who has shortlisted me for a payroll job in the same city where my husband works. It pays more than I earn currently, sounds like a good challenge, and is in the private sector. It sounds absolutely perfect. Keeping my fingers crossed!
JFK, basically I went back to the person running the contest and was like, "Umm.. I can't make it.. can you give the tickets to someone else?". I felt horrible. Haven't done that again!
