The principles of EU law
Why EU-derived rights are so important
In recent years, more and more UK workers have relied on the principles of EU law to defend and enforce their workplace rights.
In 2017 John Walker used these principles to close a loophole in UK law that enabled employers to refuse to pay same-sex partners equal pension benefits to those paid to heterosexual couples (if funds were paid before December 2005 - the year civil partnership became lawful in the UK).
This is just one example of why EU rights to non-discrimination, access to justice and effective remedies are so important.
Yet the government wants to close this route and limit workers' chances of similar wins in the future.
