CIVIL SERVANTS from across the borough plus police officers and staff are part of a series of protests over pay and conditions.
Revenue and customs staff at Crown Road office in Grays, Customs House in Tilbury Docks, the driving examiners centre in Tilbury are part of the 24-hour UK-wide strike in a dispute with the government over proposed pension changes.
Unions say the changes will leave their members paying more and working longer for lower pensions.
But the government says current pension schemes are unfair – and unaffordable because people are living longer.
Meanwhile, about 20,000 off-duty police officers are expected at a rally in London to protest against cuts.
Among the public sector workers taking part in the 24-hour strike are civil servants, NHS workers – including paramedics – border force staff and lecturers.
Gail Cartmail, from the Unite union, which represents NHS workers and others told the BBC, members had rejected the proposals in a vote “by a very large majority – 94%”.
“What the proposals mean is they will have to pay more, work longer and get less and they have said, by this very large majority, enough is enough,” she told BBC News.
But Conservative party chairman Lady Warsi told the BBC workers were being asked to “to work a little bit longer and to pay a bit more but they will be guaranteed a pension which is index-linked and inflation proof”.
“I’m disappointed that a handful of unions are striving to carry on with union action which is going to benefit no-one and is going to inconvenience the public.”
The unions taking part are: the Public and Commercial Services Union (PCS), the largest civil service trade union; Unite, representing NHS workers, Ministry of Defence firefighters and others; the University and College Union; the Immigration Services Union; Rail, Maritime and Transport (RMT) union members in the Royal Fleet Auxiliary, and the Northern Ireland Public Services Alliance.
In a central London march, thousands of off-duty police officers will protest against cuts to police funding and proposed changes to pay, pensions and working conditions.
It is expected to be the biggest police rally since a protest in 2008 against a pay award imposed by the then Labour home secretary Jacqui Smith.
Police officers are prevented by law from taking industrial action.
The Police Federation, which organised the rally, says it wants to send a message to the Government that “enough is enough”.
