Isle of Man Post is warning customers to expect disruption to services from today.
More industrial action in the United Kingdom is due to begin, and is expected to affect post to and from the Island.
It's the latest industrial action by some members of the Communication Workers Union, but this time it's on a much larger scale.
While initial strikes involved areas of London and then specific parts of the country, the latest one is nationwide.
Although Isle of Man Post Office employees are not involved in the action and are forwarding all mail as normal, deliveries will be affected and is expected to have a knock-on effect until at least Tuesday.
The special delivery next day guaranteed service from the Isle of Man should run as normal, although there could be slight delays.
More action is planned in London on Wednesday.
