Johan Einarsson is an ombudsman for the Swedish Transport Workers' Association's aviation department and according to him there is a concern with the ground-based staff at Skavsta Airport who work with, among other things, real estate and field management at the airfield.

"It is uncertain, and you can understand that, especially when it happens like this at Christmas and it is clear that you can be worried," he says.

Must have a negotiation

But according to Johan Einarsson, it is so far unclear how, or if, Ryanair's message will hit the ground workers at the airport.

- What I know for sure is that we will have a negotiation where hopefully we will know more about the consequences of this. But that's all I know right now.
