A matter of time
I dont think SAS will be going on for long with its current state.
The company will have problems convincing unions about its cost saving. There are many different union departments inside SAS which each can go on strike to defend their members against any cost cutting measures.
Question in the end is likely will they go outright bankrupt or being bought by another company. In any case it will mean total restructure of the company and loss of jobs and employment contracts which very likely would have to be negotiated from scratch as no other company would accept the current conditions....SAS is simply to expensive.
