DH has worked for the same company for nearly 30 years, since he was a teenager. A few years ago the company had a serious accident at work where a few employees were injured and there was a court case where the company was found negligent.
Shortly after that the company brought in safety reports for each area of the factory and got staff to fill out these safety reports. They were supposed to be voluntary. DH refused to do them as his area is extremely unsafe with fire exits often blocked, things just dumped all over the place and stacked in really unsafe ways, unauthorised access by all sorts of people who shouldn't be in there. The problem is that the whole area is covered by three departments and no-one takes responsibility for the area. DH felt is was a box-ticking exercise and he didn't want the responsibility of saying it was safe when it wasn't.
When DH refused to do the safety report he was hounded by his manager to do them. At first he refused but after continual hassle about them he bit the bullet and did one in good faith where he pointed out all the safety issues with photographs etc. Management said he had gone 'over the top' and changed the figures he had given to suit their own agenda. He has all their emails about this and the changed report. He also has internal emails sent between managers admitting there are safety issues in the area and they are worried that there will be a repeat of an accident that took place in another factory nearby.
DH ended up on high doses of antidepressants and was referred for CBT. He told work about this and they promised that the issues in the area would be sorted out. They never have been, in fact things have got steadily worse. So much so that DH has now gone off on the sick - he has never taken any sick leave before except when he had an operation.
