TOWTEAMBASE is correct, if you worked for Servisair then you still work for Servisair until they change your contract, even if you business is branded as Swissport it is legally Servisair until they change the employee contracts, its the same with the customers they will be contracted to Servisair until their contracts are changed. I am sure Swissport have a plan for this although it does sound like they have not communicated it well to the staff by the sound of it.
