Air transport workers – flight personnel, ground staff and air traffic controllers – will walk out from 10am until 6pm local time.
Port and motorway employees will strike at times agreed locally, while ships and ferries will be delayed by eight hours from the established time of departure.
In the health sector and other sectors where services are offered on an eight-hour rotation basis, workers will strike for the duration of their shift, leading to disruptions throughout the day. However, essential services will be guaranteed.
