Staff at 65 courts in England and Wales will walk out for nine days in a bitter dispute over an "unworkable" new system which left workers having to work longer hours.
Trade union PCS today announced that strikes by legal advisors and court associates will go ahead on October 22 to 30 - adding to chaos across the legal system.
The action is separate to industrial action announced earlier this year by barristers as pressure mounts on the government to reach a deal with workers.
Workers complain they are forced to work longer hours - often until midnight - to record case results on the controversial Common Platform system.
PCS members had been due to strike last month, but postponed the action following the death of the Queen.
The system had been paused by Her Majesty’s Courts and Tribunal Service (HMCTS) for negotiations, but PCS confirmed today that these have failed.
Union general secretary Mark Serwotka said: “We’ve been left with no choice but to call strike action. Managers are ignoring the evidence in front of them – that Common Platform is simply unworkable.
“It’s adversely affecting our members’ health and their ability to do their jobs and is detrimental to the delivery of justice.
"HMCTS managers should listen to our members and stop the roll out immediately.”
Despite HMCTS saying trials were a success, a staff survey found tasks took longer, levels of stress increased, and work-life balance was negatively impacted.
Some have been forced to work until midnight to keep up, PCS said in a statement.
