Cadbury workers are having trouble securing bank loans and house tenancies because of the threat over their jobs, making their lives "so difficult", their union says.
E tu industrial strategy director Neville Donaldson said Cadbury workers were reporting "quite disturbing" experiences after interactions with prospective landlords and bank staff.
"The consequences are really starting to take effect before even the decision has been made around the closure. That's just terrible. It's just making their lives so difficult."
Bank staff and prospective landlords were questioning workers' ability to service loans or pay rent.
"What the banks are saying is if you're taking out a loan with the purpose of paying it over five years, but you've only got nine months' job security, it's a gamble for them," Mr Donaldson said.
