Re: safety standards and workers' rights, how then did we manage all these before the EU? Just a few examples:
Factory Act 1802, for the welfare of workers in cotton mills, other mills and factories
1833 HM Factory Inspectorate formed, initially to prevent injury and overworking in child textile workers. Despite fierce opposition from some politicians and employers, it expanded to cover most workplaces over the next few decades.
Factory and Workshop Act 1878, consolidating a lot of previous legislation
Threshing Machines Act 1878
First legislative moves towards safety in agriculture
Employers’ Liability Act 1880
Workman’s Compensation Act 1897
1923 National “Safety First” Association formed, with the London Safety First Council and BISFA affiliated to it
Employment of Women and Young Persons Act 1936
1956 Legal reforms require equal pay for women teachers and civil servants
Agriculture (Safety, Health and Welfare Provisions) Act 1956
Offices Act 1960
1970 The Equal Pay Act
