Over 23,000 TUI members are set to stop answering work calls and emails outside contracted hours.
The Government is being accused of failing to plan for the needs of children requiring special education support, as teachers begin industrial action today.
From today, more than 23,000 TUI members will refuse to answer work calls or emails outside contracted hours, while secondary teachers will withdraw from 'Croke Park hours' - or 'hours outside their normal timetable'.
The union says the Government has failed to engage properly on a new pay agreement, and failed to take members concerns seriously.
TUI General Secretary Tullamore's Michael Gillespie says the demand for special education resources should have been anticipated:
