The Royal Bank of Scotland (RBS) has announced the closure of 259 branches, a decision that is expected to see 680 people lose their jobs.
RBS customers have been advised that there are other branches available, each around 40 miles away in Dunoon, Helensburgh and Oban.
However, Unite union said RBS had "betrayed" local communities. In England and Wales the number of NatWest branches will fall to 655.
However, RBS hopes to limit the number of redundancies to 680 by redeploying the remaining staff.
Unite Scotland's deputy regional secretary, Mary Alexander, said: 'RBS has forgotten about the many people in food bank Scotland who can not afford to take the bus to their nearest banking facility or parents with small children who do not have access to a auto. Since 2014 the number of customers using our branches across the United Kingdom has fallen by 40% and mobile transactions have increased by 73% over the same period.
A spokesperson said that the group is "committed to ensuring our customers and communities are able to continue accessing high quality banking services", according toSky News, while noting its mobile branches and Post Office contract.
The bank is the third this week to announce branch closures and job cuts, following Lloyds and Yorkshire Building Society.
-RBS closed its "bad bank" on Thursday, after the United Kingdom government said in November it plans to start selling 15 billion pounds of shares in RBS next year, according to Reuters.
'We know it can affect people in the local area and we'll always work hard to guide you through the changes and find the best way to serve you from now on'. The government last week said it was planning to re-privatize the lender by restarting share sales by the end of the 2018-19 financial year.
But it still expects to report an annual loss for 2017 - its tenth in succession - as it faces an imminent fine from the US Department of Justice over its sale of toxic mortgage bonds in the run-up to the crisis.
