Country: England - UK
Field: Software Development (Not customer facing)
I was at the work summer party the other day, and asked my boss if I could dye my hair blue; he's pretty high up the chain (CTO) and he told me: yea, it would be fine. However the owner of the business is a bit of a loose cannon, and although they are not around much (once or twice a month) they might not like my new beautiful blue hair!
So, since the CTO (my manager's manager's manager; fully 3 levels above me, with only the owner above him) said it's OK, if the owner decides they don't like my blue hair, can they fire me?
-- Edit -- This is not about will eccentricity hinder my career, it's specifically "I have gotten permission to change my personal appearance, can my employer (in the UK) dismiss me even though the business has given me permission."
The questions also is not about "will this affect my career growth", or the 'other' ways they can get rid of me. I'm not even concerned about being 'gotten rid of' I'm specifically asking about "Can I be dismissed if I make a change to my appearance that I have permission to make"
