Debenhams workers will protest outside Bank of Ireland branches in Newbridge and 4 other locations today.
BoI is a part owner of the firm's Irish arm.
Debenhams is in liquidation, which has prompted the closure of all 11 stores, including Newbridge.
Around 2,000 people, including those working at in-store concessions, have been made redundant.
The workers received redundancy notices last week from the liquidator.
The protests begin at midday.
