I would be interested to know the full, non media-fied version of this story. If she did indeed turn up to the interview dressed as a 'goth' but was told during her training that she would be required to adhere to company grooming requirements, then I would imagine she has no case against JQ. If she were not made aware of grooming requirements at any time during the training or her probation, and was then told after that she had to change her appearance, well I would presume thats a different story altogether.
Either way, most (all?) people know that airlines have quite strict grooming standards for all front-line staff - forgive me for being presumptuous (yes naughty Sinala1 I know), however I thought that would be common knowledge?
Lets hope time brings out the full, unabridged facts of this story.
