Re: @Wolfclaw
From roughly 1978 to the present, I've not worn a tie at work. My first work was in engineering and often had to go to the shop floor or take equipment into the field for testing. Ties were a no-no as a) they got in the way and 2) a safety hazard. When I changed career paths to IT, I kept the same philosophy... no tie as it's a safety hazard and the bosses agreed.
