The EU is blamed for a lot of unnecessary legislation but Health & safety isn’t one of them as the UK is the leader in that field.
Whilst some people feel that our legislation is an imposition, it gives us an enviable record of being one of the safest countries in the world. And, a lot of our regulations were in place well before the EU imposed its Directives on Member States – so it does seem like where the UK leads, the EU follows! Many of us have seen the lack of attention to health and safety in many European countries and probably share the opinion that the UK complies with all of EU legislation, to the letter, whereas many other member states ignore it.
Leaving the EU really won’t affect this. Staying in probably won’t either.
