Barefoot at Work
I'm a sound engineer for a recording studio in Los Angeles, and the managers don't care if I'm barefoot during the day. I usually wear sandals into work and take them off as soon as I get started.
I'm a freelance journalist, so I can work barefoot when I'm writing stories or on the phone and just have to wear shoes when I'm doing in-person interviews or covering an event.
I'm a teacher in a school with a relaxed dress code for teachers, so I usually teach barefoot.
