THE postal service has witnessed major changes over the past 20 years since the last change of uniform in 1987.
Then, the cost of a domestic stamp was 24p and fewer than a million letters were sorted by hand and delivered each day.
In 2011, a stamp costs 55c, while twice the volume of mail, around 2.5 million items a day, will be delivered to double the number of addresses due to the building boom.
There are also one-fifth more collection and delivery staff -- around 6,000 -- than when An Post was formed back in 1984 from the old Department of Posts and Telegraphs.
Now, the postal service is dealing with more packet-type mail in larger envelopes, with online shopping witnessing a 15pc increase year-on-year over the past five years.
