Louisa Taylor worked there for almost 20 years.
A former Thomas Cook employee from Buxton says everyone at the airline is 'devastated' following its collapse yesterday.
They ceased trading in the early hours of Monday morning after failing to agree a deal with creditors.
Louisa Taylor, who lives in Buxton, worked for the airline as a Cabin Manager.
She'd been there for nearly twenty years, and told Peak FM it's been an awful few days;
"I'm in total shock. It feels like I'm in mourning, it's horrendous-I can't get my head around it.
"All my colleagues feel the same, they're in utter denial. Nobody can quite grasp that they aren't going to put their uniform on again or fly around the world with their work mates.
"I woke up this morning, and for a split second I'd forgotten, and then the realisation hit.
"It's an awful situation and so sad for everyone connected to the airline."
Meanwhile, the government's putting together a task force to support staff at Thomas Cook who've been made redundant.
