UBER drivers are set to go on strike in three cities across the UK today.

Here’s what we know about the industrial action.

A trade union called on Uber drivers to strike on Tuesday for 24 hours by not signing into the app.

Uber has around 60,000 drivers in Britain and earlier this year won back its right to operate in London after it was stripped of its licence by the city's regulator.

The Independent Workers Union of Great Britain (IWGB) expects hundreds of drivers at least to participate in the industrial action from 1pm on Tuesday by not signing into the app. Protests are also planned outside Uber's offices.

Why are drivers protesting?
Drivers are pushing for higher fares and more working rights.

In Britain, its drivers are self-employed, entitling them in law to few workplace rights, prompting the IWGB and others to launch legal action.

A Court of Appeal hearing over workers' rights at the company is due later this month.

Uber drivers are not obliged to work particular hours by the firm and choose when to sign in and out of the app.

The Silicon Valley-based company said it had improved its offering to drivers in recent months.

"We’ve introduced dozens of new features, including sickness, injury, maternity and paternity protections," said a spokesman.

"We continue to look at ways to help drivers increase their earnings and our door is always open if anyone wants to speak to us about any issues they're having."

Uber has faced protests and legal action around the world as it disrupts traditional operators.
How long will the strike last and which cities are affected?
London, Birmingham and Nottingham are all set to be affected by the 24 hour industrial action.

The strike on Tuesday will be the first time that a trade union has taken strike action against Uber.

IWGB is calling for public support for the striking drivers by asking customers not to "cross the digital picket line" by using the app during the strike.

Drivers will be staging protests outside of the company's officers in London, Birmingham and Nottingham.

The union is currently engaged in legal efforts to secure private hire drivers rights through the courts, and has cases against Uber, Green Tomato Cars and A2B Cars.

The drivers are demanding an increase in fares to £2 per mile, up from £1.25 in London, as well as a 10% reduction in commissions paid by drivers to Uber.

They also ask for an end to "unfair app deactivations", which they argue amount to de facto dismissals.

Finally, the drivers request that Uber apply the employment tribunals' judgements and "immediately implement employment conditions that respect worker rights for drivers, including the payment of at least the minimum wage and paid holidays".
