Strikes Update: How Friday 17 February’s walkouts will affect you

Border Force staff begin a four-day strike series on Friday during the semester for many UK schools.

Industrial action is being taken by British staff working at the Port of Dover, but also at Calais, the Port of Dunkirk and the Coquelles Channel Tunnel Terminal.

People arriving in the UK on Friday should prepare for border disruptions, according to the Home Office.

Rescue workers in the West Midlands and Northern Ireland are also on strike on Friday.

The action is being organized by union Unite, which says essential emergency coverage will be in place.

The PCS union expects 1,000 of its members to dock at the ports of Calais, Dunkirk and Dover and at the Coquelles Channel Tunnel Terminal between Friday 17th February and Monday 20th February.

Military personnel and officials have been trained to intervene and carry out border controls, although military personnel will not travel to France.

Still, the government said people should prepare their families for longer waits at border control.

People should use eGates whenever possible and check with the operators before travelling, it said.

Hundreds of Unite union members went on strike in Northern Ireland and the West Midlands on Friday. People are still advised to call 999 in an emergency.

Ambulances continue to be dispatched to the most life-threatening calls – known as Category 1, which includes cardiac arrests.

Patients who need life-saving treatment such as kidney or cancer treatment are also transported.

Less urgent calls – known as Category 2, which includes some strokes and severe burns – may have to wait longer than usual for an ambulance.

The NHS advice reads:
