Letters will now be delivered every other day in Guernsey.
Guernsey Post says only delivering on Mondays, Wednesdays and Fridays will allow the team to prioritise parcels, and help them to work in the most "safe and effective" way.
Both letters and parcels from the UK will now arrive at 12:30pm each day, and will be delivered the following day.
Meanwhile, Guernsey Post has also postponed its annual price rise to its public tariff.
The annual increase was due to take effect from today (1 April), but has now been suspended until 1 July.
