My girlfriend is graduating from college right now and starting her professional career in a medium sized, rather traditional company in Germany (~12k employees worldwide). While being a teenager she self-harmed and has easily visible scars on her left arm. Although the reason for it, the psychological issue, has gone, the scars remain as a mark from that time. Now, as the summer is approaching, she is thinking about wearing short-sleeved shirts at work, which she avoided until now. She is insecure regarding the reaction of colleagues, heads, etc. and concerned about being seen as an unstable and mentally ill teenager she was years ago instead of the person she is now.
Do you have any advice or experiences whether hiding those scars is better in prospect of her professional career, as to not offer the past hard times? Or are companies managing to deal with past mental issues professionally in your opinion?
Thanks a lot.
