It forms part of the largest one-day strike over pay by public sector employees since 2010. More than a million council staff, health workers, teachers, firefighters and civil servants will take industrial action in a nationwide strike over pay and cost-cutting.

Caroline will join workers in the city for a march against Government austerity measures.

She said: "It is very clear that austerity isn't working.  People are struggling with poverty pay, the cost of living is rising and it's time the Government recognised the immense value of all the workers who provide us with crucial services every single day.  Strike action is the option of last resort, and the decision to take part will not have been taken lightly.   But the public sector in the UK has, for decades, been systematically attacked. Workers are bearing the brunt of this, and are being expected to pay the price for an economic crisis not of their making."

 As well as joining them in the march, Lucas pledged to continue representing workers’ rights in Parliament. She said: “It is simply unacceptable that workers continue to suffer pay cuts and freezes and I’ll continue to lobby the Government to do the right thing by increasing public sector pay.”

Davy Jones, Green Party parliamentary candidate for Brighton Kemptown, will also join the march in Brighton and Hove.

Mr Jones said: “People have had enough of the Government’s austerity measures. I fully support the rights of workers in the public sector to strike in defence of their jobs, wages and pensions. Our public sector workers did not cause the economic crisis – they should not have to pay for it.”

Councillor Christopher Hawtree, Deputy Chair of Economic Development & Culture Committee, said: “Our local public sector workers are the people who keep our communities running. They deserve a fair wage – a Living Wage – and it’s time the Government paid up. That our workforce should have their pay cut and frozen for years on end is a scandal. That a raise is unaffordable is a myth. It is affordable. It is do-able – and it is the right thing to do. That’s why I’m supporting Thursday’s strike in Hove and Brighton.

"My life has always been immeasurably improved by people who choose, often at some cost to themselves, to work in the public sector. Librarians are but just one profession whose great work resonates through the community - and down the years. Without such people’s hard work, the country could not function. Their great worth should be recognised - not sidelined."

Thousands of people around the country will forgo a day’s pay to demonstrate their unhappiness with the Coalition’s policy of frozen and restricted pay on public sector workers.
