No simple answer here as it's always going to be a personal choice. Virgin is a deeply unhappy company at the moment and there is no sign things will improve. Quite the opposite in fact. The company will try and use every trick in the book to adopt a new scheduling agreement that will doubtless see pilots working harder under the false promise of improved bid satisfaction if the pilots are dumb enough to vote for it.
Is it all bad? Well no actually. But the odd good trip still to be had doesn't pay the mortgage, won't compensate for a possible 15 year wait for command and the inherent lack of job security in a company that does not value it's pilots.
