Services between Jersey and the UK will not be affected by proposed industrial action on Monday 14 January, according to Ports of Jersey.
Customs & Immigration officers will walk out all day following the ongoing, unresolved pay dispute between the States of Jersey and its staff.
Passengers flying or sailing to and from the UK are advised to continue with their travel plans as normal.
However, Ports of Jersey says the proposed strike is likely to impact the two arrivals from, and one departure to St Malo.
They say around 113 passengers could be affected and they are liaising with Condor Ferries for further updates.
Ports of Jersey is reminding islanders that although there will be no customs presence at either the Airport or Harbour on Monday, customs checks will remain in place at departure points so travellers should not exceed their usual customs allowance.
