Thousands more predicted to follow suit according to law firm.
Hundreds of Uber drivers have joined GMB’s case against Uber – with a total of 50 now having proceedings issued.
GMB, the union for Uber drivers, has prepared the latest tranche of 25 drivers with a solid case for compensation after not being provided with basic rights by the California-based company.
Law firm Leigh Day, working with GMB to assess the claims, predict thousands of drivers could potentially join the group action.
The announcement follows a historic ruling in the London Central Employment Tribunal in October  when it found that a group of Uber drivers were not self-employed but were workers.
This means they are are entitled to be paid at least the national minimum wage and holiday pay , a landmark has major implications for more than 30,000 drivers across England and Wales.
GMB has joined forces with law firm Leigh Day to bring the drivers’ claims to court.
Maria Ludkin, GMB legal director, said:
“We are delighted so many hundreds of drivers have contacted us and we are working as fast as we can to get them ready to issue proceedings.
"We will have the next large group ready to go early in the new year."
Nigel MacKay, from Leigh Day, said:
“The judgment at the Employment Tribunal does not prevent Uber drivers from working flexibly, it simply ensures that whilst they are working the drivers receive the rights that every other worker is entitled to.
“Since the judgment was issued, we and GMB have spoken to hundreds of Uber drivers who wish to claim compensation for Uber’s failure to provide these entitlements in the past, as well as to ensure that they are paid at least the national minimum wage and holiday pay in future.
“We are issuing claims on behalf of those drivers and the latest 25 claimants who have joined the legal action will be included in claims for compensation. We anticipate issuing further claims on behalf of drivers in the coming weeks.”
The law firm predicts the potential number of claimants could be thousands of drivers who can claim for the money and benefits they have not received as workers for Uber.
Notes for editors
 GMB found last year that a member working exclusively for Uber received just £5.03 per hour in August after costs and fees were taken into account, significantly below the national minimum wage of £7.20. Lawyers for the drivers also argued that Uber acts unlawfully by frequently deducting sums from drivers’ pay, often without informing the drivers in advance, including when customers make complaints.
