Which is protection you voted to remove in voting to leave the EU. I actually wonder if some of the unions were anti-EU because of the protection to worker's rights offered under EU legislation. Trade union membership has dropped a lot since the 1970s and having the EU guaranteeing holiday entitlement, maximum working hours, paternal leave, statutory sick pay etc. doesn't exactly incentivise people to join trade unions in the same way as they did in the 1970s. However, once we leave the EU the likes of Boris Johnson can remove that 'EU red tape.'
