At a glance: Impact of tomorrow's public sector strike

More than 300,000 public sector workers including nurses, doctors, teachers and civil servants, will engage in a 24-hour strike tomorrow over delays in agreeing a new public sector pay deal.

Here is a breakdown of where the biggest impacts are likely to be felt.

School closures

The main teaching unions, including the INTO, ASTI, TUI and IFUT, are all taking part in tomorrow's strike which means that most schools, colleges and universities will be closed for the day.

Special Needs Assistants, who are represented by the Fórsa trade union, will also be on strike.

Expect to see pickets at the gates of schools right across the country.

Parents should already have received communications from their schools advising them of the closures.

Health services

Thousands of medical appointments will be cancelled tomorrow as a result of the strike.

The HSE has warned that there will be "significant and widespread disruption" to many of its services.

The cancellation of all non-urgent healthcare services across hospitals and community settings is expected.

This would include routine hospital procedures, outpatient appointments, community-based services such as day services, clinics in primary care services and other scheduled care services.

"Emergency departments, ambulance services (curtailed service) and other critical, time-sensitive healthcare services, such as urgent cancer treatment and dialysis, will continue," the HSE said.

"GPs, GP out-of-hours and pharmacists will remain available in the community," it added.

Dentists working in the HSE will also join the strike, the first time in history the Irish Dental Association has served notice of industrial action.

Courts service

Almost all court sittings will be cancelled because of the strike.

"Given the level of involvement in the industrial strike proposed for Wednesday and in consultation with the unions, the Courts Service will not be able to support courts and open public counters on Wednesday," the Courts Service said in a statement.

The only exceptions are emergency domestic violence and childcare applications, An Garda Síochána applications to remand an accused person in custody where station bail has not been granted and High Court sittings to deal with injunctions to protect life, health, safety or welfare.

Leinster House

Leinster House will be closed because of the strike.

Sittings of the Dáil and Seanad, as well as Oireachtas Committee hearings, have all been suspended for the day.

In a letter to TDs and senators, the Clerk of Dáil Eireann Elaine Gunn wrote: "Members are advised that all buildings on the campus, including Leinster House, will be closed on the day for health and safety reasons and security considerations associated with opening and closing buildings."

The Government had initially pushed for the Dáil sitting to go ahead tomorrow with a suggestion that unions might give officials a derogation.

Opposition party members had insisted they would not cross picket lines.

Some bus routes may be affected by picket lines

The National Bus and Rail Union said it acknowledges that Dublin Bus and Bus Éireann employees are not participating in the industrial action but has told its members not to pass picket lines.

"Notwithstanding that position, NBRU members operating Dublin Bus services may, in the course of an official route, encounter official picket lines at colleges, hospitals, ports and other premises affected by the industrial action," NBRU General Secretary Dermot O'Leary wrote in a message to members.

Members "should not be expected to drive a vehicle across, enter through, or otherwise cross a clearly identifiable official picket line established in connection with the industrial action," Mr O'Leary wrote.

Driving tests

Driving tests scheduled for tomorrow have been cancelled because staff from the Road Safety Authority will be taking part in the strike.

The RSA said it regrets the inconvenience caused and that affected applicants will be contacted directly.

"Every effort will be made to provide a new test invitation as soon as suitable test slots become available," the RSA said.

Local authorities

Local authorities across the country will see services severely disrupted, with many libraries expected to close.

Civil servants working across Government departments and State bodies will also be on strike.

All heritage sites and parks operated by the Office of Public Works (OPW) are expected to close on Wednesday.

The only exception is the Phoenix Park, where roads will be open.

What will not be impacted?

While members of An Garda Síochána and the Defence Forces are public sector workers, and are covered by public sector pay agreements, they will not be engaging in strike action as they are legally prohibited from doing so.

Public transport services are also expected to operate as normal.
