I only know the generalities of the situation, but having seen the fallout from some of these type of things at a regional I’d imagine if the CA was in fact wrongfully terminated it will take time making its way through the courts and then they’ll eventually get their job back with backpay plus maybe some extra etc etc... It’s just a process.
The reality is that an employer can let anyone go at any time for any reason they choose. Whether it was wrongful or not is then determined by the courts if that is the avenue the wronged party wishes to pursue. It stinks, but it’s the truth.
