The redundancies were first reported by Fagbladet 3F, the media produced by trade union 3F, which has over 400 members with Gate Gourmet.
The company provides the majority of catering services at Copenhagen Airport. Around 600 of its 800 employees are 3F members.
Staff were expected to receive notification on Wednesday of whether they will be kept on or let go.
“This is a terrible situation. I’m deeply upset by the impact of this on so many people,” Gate Gourmet union representative Jan Thomsen said.
The company is the latest of several Copenhagen Airport firms to announce job losses as a result of the impact of the coronavirus crisis on air travel.
Last month saw around 2,500 people lose their work with companies including SAS Ground Handling, Aviator and Sodexo.
Given that many airlines are currently not serving food in-flight as part of measures to hinder spread of coronavirus, Gate Gourmet remains vulnerable to the current situation.
