Tattoos and piercings where visible are not allowed and reason for immediate dismissal. Only exception are earrings for female pilots or cabin attendants.
That is pretty clear cut in our manual and backed up by labor law.
LOL ...
How tattoos and piercings can affect the ability of a pilot do his work in the state of the art?
Who can explain it in detail?
It seems to me that this labor law has nothing to do with the art of flying or flight safety ...
Some might even perceive the scent of discrimination ...
