Nearly 80 members of staff at a Cardiff hospital have been left "broken" by a court ruling that means they owe thousands of pounds in parking tickets, a campaigner has said.
On Friday, a judge at Cardiff Civil Justice Centre ruled private company Indigo could collect the charges from University Hospital of Wales staff.
Campaigner Sue Prior said one nurse had tickets amounting to £150,000.
Ms Prior said: "It's horrendous. Some of them [staff] are broken. They're scared stiff, petrified, they feel sick. This affects everyone from cleaners to doctors."
"It's not really the outcome that we wanted and what we earn doesn't really cover the fines," she added.
Staff nurse Felicity Richards added: "I have to allow 45 minutes to an hour extra to park my car every morning to find somewhere to park.
"By the time I get into work there are usually no parking spaces and I have to park off site and quite often I have to park a 20 to 25 minutes walk away."
Ms Prior said staff had permits which allowed them to park in designated areas for £1.05 a day.
But she said a lack of spaces meant staff had been forced to park in unauthorised areas.
Indigo has had a contract to manage and maintain the hospital's car parks for several years and has 1,250 spaces there.
Ms Prior said she had been campaigning on behalf of staff because two of her children were born blind at the hospital, but after medical intervention now have some sight.
"I had to help. Without those people and the NHS my children would be blind," she said.
Indigo Park Services UK and Cardiff and Vale University Health Board have been asked to comment.
