After the GG dispute the yellow card was shown to many re bullying and harrassment. If there is a hint of that with any "new fleet" just watch the management pounce. Any attempts to "make things difficult" will be difficult because the unions have brilliantly forced the concession that new fleet will all fly together and there will be no fleet mixing. Genius! Any attempts to victimise new fleet crew will be stamped on and the perpetrators disciplined.
