From the other side of the coin.... This was me 30 years ago, in my 20s. I had an inherited kidney issue and was awaiting surgery. I knew I had a body odour and the panic of not being able to do much about it, made it worse.
Unbeknown to me, my manager called in HR from Head Office who travelled from Milton Keynes to London to tell me about it. It was dressed up as 'Could you take your shorthand notebook to this meeting,' disguised as these visitors from HR need your secretarial assistance. This was to divert attention from others in an open plan office.
So, still unaware and sitting there ready to take notes, these two ladies brought up the subject of body odour. It was not end of day, and a total shock made worse by the fact these ladies were so glamorous, I felt like total shit in their company.
I was mortified, truly mortified. We discussed home arrangements, washing machines, cotton clothing, soaps, etc and then my medical issue. I went to the toilets, sat in a cubicle and cried. I could not look my manager in the face again, and left soon afterwards. Had my surgery, got another job and the issue never presented itself again. Plus, I make 100 per cent sure it won't.
There's a way to do this, and the HR ladies ignored sensitivity and went barging in. I still cringe. Don't be that person!
