Royal Mail has stopped all Saturday letter deliveries because of coronavirus.
From this weekend onwards the postal service will no longer deliver letters on a Saturday.
But Special Delivery, Tracked, all non-account services and "most other parcels" will continue being delivered six days per week.
Saturday collections from businesses, post office branches and post boxes also continue as normal – reports Mirror Online.
A video for staff by Nick Landon, Royal Mail's chief customer officer, said staff have been under "incredible pressure" for a month and "need some relief".
He said: "We want to lessen the load for deliveries across that weekend, making us focus on the parcels to clear all of that traffic.
A statement posted on Royal Mail's website said: "Our postmen and postwomen are working very hard across the UK in challenging conditions.
"As we said at the start of the coronavirus crisis, there will be some disruption to services.
"Relevant factors include high levels of coronavirus-related absences and necessary social distancing measures.
"We understand the importance of the postal service in keeping the UK connected at this time.
"We have also listened to our hard-working colleagues who have asked us to ease the additional burden on them if possible. As a result, we are making some temporary changes to postal services.
"Customers should continue to post both letters and parcels as usual on Saturday. We will continue our Saturday collections from businesses, post offices and post boxes as normal."
The statement added: "From 2 May we will temporarily no longer deliver letters on a Saturday.
"We will continue to provide a letter delivery service from Monday to Friday as normal. We will continue to deliver Special Delivery, Tracked, all non-account services and most other parcels from Monday to Saturday across the country."
