Huddersfield will be badly hit by a strike involving thousands of workers on Thursday.
At least six unions are set to walk out as part of a long-running dispute over pay, pensions and cutbacks and that will have a massive impact on public services.
All Kirklees Council buildings are set to remain closed and a number of schools could will be shut.
Striking council workers will make an exception to help three couples who have booked weddings at Dewsbury Town Hall and Huddersfield Town Hall by opening the buildings for the wedding parties.
It is set to be the biggest strike by public service workers for many years and the situation in Huddersfield will be replicated in towns and cities across the country.
Members of the National Union of Teachers (NUT) will be on strike as will members of UNISON, UNITE, GMB, PCS and the FBU.
The action will see teachers, council employees, civil servants and firefighters all taking action on the same day.
A big rally is planned for Huddersfield on Thursday morning and union officials expect that to be attended by more than 2,000 people.
Paul Holmes, Unison branch secretary for Kirklees, expects most of their 7,000 members working for Kirklees Council to be on strike.
He said two other local government unions, the GMB and Unite, have a further 1,500 members in the authority and they too are likely to walk out.
It will mean there will be no housing offices open, no caretakers for the schools and no-one working in libraries.
Mr Holmes said: “No-one wants industrial action but this particular dispute has been supported by more people than ever before.
“A lot of people are fed up with the way the pay and pensions talks are dragging on and with the increasing pressure because of repeated cuts.. The last time we took action we were supported by 90% of our members and this time it could be more”.
Council offices and schools across Calderdale are also likely to be closed.
Calderdale Council has about 4,000 Unison members among its workforce as well as hundreds employed by Unite and the GMB.
The NUT has hundreds of members in schools and colleges and many of those are expected to take part in the day-long dispute.
Teachers who are NUT members are striking in relation to their long running dispute with the Secretary of State for Education Mr Michael Gove over pay, pensions and workload.
Ian Stevenson, Yorkshire NUT Regional Secretary, said: "The Secretary of State for Education is laying waste to the education system in concerted attack on teachers and the education service. NUT members on Thursday taking strike action will be proud to stand up for teachers, for education and for pupils and parents.
"Those who work in the public sector are essential for the well-being of our children, our elderly and the vulnerable. Many work in difficult low paid employment, it is wrong that they continue to take the brunt of the government cut backs attacking their pay and pensions”.
The West Yorkshire Fire and Rescue Service will see firefighters on strike from 10am to 7pm.
The Fire Brigades Union (FBU) is holding its 15th strike.
Asst Chief Fire Officer Dave Walton called the announcement of strike action “extremely concerning”.
He said: “We are very disappointed that we are in this position once again and are forced to divert yet more time and resources towards providing contingency arrangements.
“They will not provide the normal level of fire cover across West Yorkshire so I ask the public once again to take extra care and not to place any unnecessary, non-emergency demand on our reduced resources.”
