Ambulance workers will walk-out later today in the latest strike in the long running row over shifts and working hours.
Unite members at the Yorkshire Ambulance Trust plan to strike from 3pm this afternoon until 7am tomorrow morning.
The union claims proposed longer shift patterns could lead to staff working for up to 10 hours without a meal break and could affect patient safety.
The Tust said it would take steps to "maintain operational cover".
Ian Brandwood, Executive Director of HR at the Trust, said: "We are very disappointed that Unite the Union has decided to go ahead with strike action this weekend despite recent constructive talks with senior representatives at the union."
Care workers in Doncaster will go on strike today for another 7 days after a breakdown in talks between UNISON, ACAS ( the Government Arbitration and Conciliation Service) and Care UK.
Around 150 UNISON members will take further 7 day strike action over Care UK's threat to slash their pay and conditions. The strike will start from 7 a.m.
UNISON Regional Organiser Jim Bell said: "We are bitterly disappointed that talks to resolve this strike in a fair and sensible way have been thwarted by Care UK who are still proposing to cut take home pay by up to 50 per cent."
Firefighters across the region will walkout for a fourth time today in a row over pension proposals.
Members of the Fire Brigades Union will strike between 10am and 2pm.
The industrial action is over Government proposals to cut pensions to fiefighters who are forced to retire early due to declining fitness.**
Firefighters who are forced to retire before 60 as a result of declining fitness could now receive pensions of just over £9,000 a year .** **
** As well as striking today firefighters are also voting in a ballot over additional forms of industrial action.
Five hundred ambulance workers have joined picket lines across Yorkshire and North Lincolnshire for a 12 hour walk out.
Members of the Unite Union are taking action because they say the Yorkshire Ambulance Service NHS Trust are risking patient safety, by allowing new emergency care assistants to work with paramedics after only six weeks training.
Over the next five years the trust has to cut their budget by forty six million pounds. They say they'd like to reassure the public that the level of disruption will be minimal during industrial action.
Health Secretary Andrew Lansley say he is "disappointed" at the doctors' decision to take industrial action.
Dr Richard Vautrey, deputy chair of the BMA's GP Committee, and a GP in Leeds himself, describes why doctors feel moved to take industrial action.
GPs across the region are taking industrial action today in a row over pensions.
It is the first walkout of its kind since 1975 and will last for 24 hours. Doctors say they are being treated "differently" to other civil servants.
Plans by the Government could see the retirement age for doctors rising from 65 to 68 by 2015, with contributions to pension schemes also increasing.
Staff who work for the Driver and Vehicle Licensing Agency (DVLA) are walking out across our region today.
It is in protests to threats to close 39 offices. 1,200 people who work in the DVLA's local and enforcement offices will go on strike for two hours. It is part of action across the Department for Transport, who are taking industrial action against cuts to pensions, jobs and pay.
Unions claims the DVLA closures will put jobs at risk, but also put an end to face-to-face services the offices provide, which cannot be dealt with online or by telephone.
