The UK government made a commitment Wednesday to not reduce the standards of workers’ rights from as they are in European Union laws post Brexit, and any new legislation changing those laws will be assessed as to whether they uphold this commitment. Parliament will also be given the right to consider any future changes in the EU law that strengthen workers’ rights or workplace health and safety standards, and vote on whether they should be adopted into UK law.

“The measures will require Parliament to be given regular updates on changes to EU legislation in this area and will give MPs a choice on the action government will take in response, including whether MPs want to decide that the UK should remain aligned with the EU,” according to the government. “In preparing those updates, trade unions, businesses and the relevant select committees of Parliament will be consulted with.”

Euronews reported Prime Minister Theresa May made the pledge as part of a political strategy to help pave the way for EU-UK deal on Brexit. And the Trades Union Congress said the pledge won’t shore up workers’ rights.

“These are flimsy procedural tweaks,” TUC General Secretary Frances O’Grady said in a statement. “They come nowhere close to ensuring existing rights are protected. And they won’t stop workers’ rights in the UK from falling behind those in the rest of Europe.”

According to the government, plans call for the process to start with two EU directives coming into force after Brexit — the Work Life Balance Directive and the Transparent and Predictable Working Conditions Directive. The former provides new rights for parents and caregivers such as two months of paid leave for each parent until the child is 8. The latter sets terms of employment for workers by their first working day and provides for more stability for those working shifts.

“After Brexit it should be for Parliament to decide what rules are most appropriate, rather than automatically accepting EU changes,” May said. “When it comes to workers’ rights this Parliament has set world-leading standards and will continue to do so in the future, taking its own decisions working closely with trade unions and businesses.”

An extra package of measures to strengthen workers’ rights was also brought forward. They include bringing a range of enforcement bodies under one roof. The government noted that right now the HMRC enforces the national minimum and living wages, the Gangmasters and Labour Abuse Authority investigates reports of exploitation and illegal activity in the workplace, and the Employment Standards Inspectorate protects the rights of agency workers.

Proposals for a single labour market enforcement body will be brought forward in the coming months. One example of its power would be to ensure agency workers are not underpaid.
