We are in the UK and a friend of mine is changing roles within her job into one in which she has to wear non-slip safety shoes (PPE - Personal Protective Equipment). The standard shoes that my employer provides give her a bad back, possibly as they are not supportive enough. She has tried some good-quality insoles of my own, but these do not help enough.
She has offered to buy her own shoes, but my employer says that this is not acceptable.
I've searched for UK legislation on this, but can't find anything that helps her with regard to her being made to wear the shoes they supply. She is not disputing having to wear approved shoes.
How can she approach her employer about getting an alternative shoe choice approved?
Edit: Getting a medical note from a doctor would not be a problem. I know that employers have to supply suitable ergonomic etc equipment and we are wondering where this requirement and the PPE legislation cross over.
