The UK is experiencing levels of industrial action not seen in decades, as public sector workers stage walk-outs in disputes over pay and conditions.
In November 2022, the most recent date for which data is available, 467,000 working days were lost to labour disputes – the highest since November 2011.
Strikes will be an almost daily occurrence throughout the rest of January, while several walkouts are already planned for February and into March.
Staff across transport, education, health and government sectors are demanding more pay as the nation continues to grapple with a cost of living crisis.
Watch: Teachers and nurses announce new strike action
Among the upcoming strike dates one stands out – a national day of action that will see walkouts from a range of different professions.
When is the national day of action?
A widespread day of strike action is taking place on Wednesday 1 February.
Who is striking on this day?
So far, teachers, train drivers and civil servants have confirmed co-ordinated walk-outs.
Which unions are involved?
In England and Wales, teachers who are members of the National Education Union (NEU) will go on strike over pay.
It is the largest eduction union in the UK so the disruption to schools is expected to be widespread. More than 23,000 schools in England and Wales are expected to be affected.
In Scotland, teachers from the Educational Institute of Scotland (EIS) will also be on strike in Clackmannanshire and Aberdeen as part of an ongoing pay dispute.
Train drivers who are members of the Aslef union will also be on strike on 1 February, which will affect most of the train companies in England.
Meanwhile, about 100,000 civil servants across 124 government departments and other bodies will strike over pay and conditions on the same date.
This will include staff at the Department for Work and Pensions (DWP), the Driver & Vehicle Licensing Agency (DVLA) and the Department of Health and Social Care (DHSC).
That date has also been scheduled for a nationwide protests against the government's controversial new anti-strike law.
What is the new anti-strike law?
On Monday, MPs voted to give the Strikes (Minimum Service Levels) Bill a second reading in the House of Commons.
The controversial legislation would require minimum levels of service from ambulance staff, firefighters and railway workers during industrial action, although unions and opposition MPs have condemned the proposals as unworkable.
Details of the minimum service levels which will need to be maintained during strikes have yet to be set out, and the government says it will consult on this.
Business secretary Grant Shapps said: “We want constructive dialogue with the unions and the public has had enough of the constant, most unwelcome, frankly, dangerous disruption to their lives.”
Labour deputy leader Angela Rayner criticised the bill as “one of the most indefensible and foolish pieces of legislation to come before this house in modern times”.
She added: “It threatens teachers and nurses with the sack during a recruitment and retention crisis."
What other strikes are happening?
Aslef train drivers will also walk out on Friday 3 February, while teachers in the NEU are also scheduled to strike across England and Wales again on 15 and 16 March, with regional strikes planned for 14 February, 28 February, 1 March and 2 March.
On 18 January, Royal College of Nursing (RCN) members in England will strike, along with Unison members at the Environment agency.
On 23 January, Unison members working for five ambulance services in England will stage another walkout, while Unite ambulance workers will also strike.
On 6 and 7 February, nurses from 73 Trusts in England will strike in an escalation of industrial action by the RCN.
What has the government said?
On Tuesday, Downing Street said widespread strikes on February 1 will likely cause “significant disruption” to the public.
The prime minister’s official spokesman said: “We’re in no doubt that this strike action, some of which will fall on the same day or days, will cause significant disruption to the public – whether it’s children having their education disrupted or the public trying to go about their daily lives on their commute.
“We don’t think it’s the right course of action, we continue to call unions to step away from the picket lines and continue with discussions.”
