DH has been very unlucky with his health for the last few years and so has triggered his workplace's sickness threshold for a disciplinary. He is terrified that he is going to lose his job, and naturally I am worried as well. They've suggested that he could cut his hours if working full time is too much for him, or they could offer ill health retirement, but he really wants to continue working full time (mainly for financial reasons - after years of struggling we are finally comfortable and he doesn't want to go backwards). When he's well he is more than capable of this, but he does tend to get ill more often than average (he had covid 5 times for instance) and has also been unlucky with injuries (and is waiting for an operation to repair one of them).
Does anyone have experience of these kind of meetings and what might happen if he turns down those offers? For context, he has worked for them for over 30 years, they are a large company with an excellent reputation for looking after their staff, but he has had a previous final warning for sickness (several years ago so now expired).
