VCC's a senior crew...
...Eddy don't get too cut up about VCC's working as Purser's or CSD's. The reason those of us, who had previous cc experience, were asked to do an SCCM course was to make sure that there was a pool of crew who could operate as the SCCM, in the event that the operating CSD didn't turn up.
From my own experience on the the three long haul flights I have done is that there has been a CSD on each of them and I've worked as a purser.
Have you considered volunteering to act as a Purser on your flights where the Purser has no showed or asked about doing the SCCM course to cover during the strike?
I'd much rather people with more experience were doing the job, but at the end of the day this is about getting as many of our customers as possible to where they want to go safely.
