A possibility ?
The freighter operation will become a separate entity with different terms & conditions from mainline , just like SQ , CX et al . Should you not have an individual contract clearly stating these terms and the return to the pax operation , seniority & requirements for upgrade etc + compensation for breach of contract . The fact is you may well find yourself trapped in a totally different company . Cynical perhaps ? This is a chance to avoid being conned , pls think carefully . History has a tendency to repeat itself here . See previous posts !
