Thousands of civilian police staff - including 999 call handlers - are set to strike on New Year's Eve, the PCS union has said.
The planned strike would coincide with a walkout by London firefighters and could see around 7,500 civilian workers taking action on one of the busiest days of the year.
The strike was planned after a 1% pay rise was imposed by the Metropolitan Police last month, which is below inflation.
Police community support officers, 999 call handlers, detention officers in custody suites, and a range of administration and professional support staff are among those due to take action.
The Met said they were "confident" they have good contingency plans in place in the event of a strike.
London Fire Brigade is asking people to get a takeaway rather than cooking whilst drunk this Friday and Saturday night as the Fire Brigades Union is on strike.
The service says young, well-educated, professionals cause more than a quarter of all accidental house fires in the capital, often by attempting to cook at home when drunk. This greatly increases the risk of someone having a serious fire which could destroy their home or, even worse, kill them
Brigade figures show:
• Two fires a day happen after Londoners have been drinking.
• One in four people who die in a fire has alcohol in their system.
• Three quarters of alcohol related fires are caused by cooking under the influence.
• Over half of these fires happen because someone has fallen asleep.
London Underground workers are due to start voting on whether to strike in the New Year.
The result of the ballot, in protest over proposed job cuts and tube office closures, is due on January 10th.
Parcel deliveries in London are expected to be severely hit today as UPS workers stage a 24 hour strike. The action is part of a row over workloads and alleged bullying.
120 staff at the Camden depot began a walkout at one minute past midnight this morning. Members of the Unite union at the UPS London base voted by 9-1 in favour of industrial action.
A strike by London firefighters planned for tonight has been called off.
Members of the Fire Brigades Union had been due to walk out for five hours in a row over pensions.
Strike action by firefighters has been called off after progress was made in a dispute over pensions.
The walkout was due to last from 6.30 to 11.30pm tomorrow and reduce the number of fire engines operating in London from 169 to just 27.
The Fire Brigades Union said it had been presented with a similar deal to one made by the Scottish Government, covering the retirement of firemen and women aged between 55 and 60.
The London Fire Brigade is asking people to take extra care in their homes ahead of a second planned national strike tomorrow.
The walkout, which will take place between 6.30pm and 11.30pm tomorrow, will see the number of fire engines in London reduced from 169 to just 27.
Plans are in place to provide a contingency level of emergency cover across the capital during the strike, but officials have warned less urgent incidents may not be attended.
The strike is part of an ongoing dispute over pensions.
London firefighters are to strike for five hours on Saturday 19 October over pensions, the Fire Brigades Union (FBU) announced today.
The union said members will down tools from 6.30pm to 11.30pm. General secretary Matt Wrack said: “We had hoped our first strike was enough to show government that firefighters could not be more serious about protecting public safety and ensuring fair pensions.
“We hope this second strike will mean both governments will be willing to discuss the full range of concerns that firefighters and the general public have expressed."
Firefighters vote to strike: 'It's not too late for common sense to prevail,' says FBU leader: http://t.co/smkNJJU9Rg
78% of FBU members vote to strike. Turnout of 60% solid and respectable, and very much at upper end of spectrum for union ballots.
The London Brigade said it will be issuing further fire safety advice in the lead to any potential strike date.
London Fire Commissioner, Ron Dobson, said:
It’s a pity that we are in this position, but we are prepared and our contingency fire service is ready to operate during a strike. Last month we temporarily removed 27 fire engines from stations across London and these will be used by contingency crews to provide a level of fire cover for the capital.
During a strike, my advice to the public would be to take even greater care to prevent fires from breaking out at home. Simple steps like keeping a really close eye on cooking and making sure cigarettes are disposed of properly can make all the difference.
