I presume for safety all those on frankfurt base have been removed from flying and all the who were refused VSS have temporarily been removed from flying as well. In a first world airline to be offered VSS with a short timeframe and the pressures of that decision and some under the cloud of visa issues you would assume the safety managers would advise that these crew members would need some time to re-adjust again. As the job is not one of a paper shuffler where your error may only be a spell check issue.
