Alright, I'm going to give you the extreme benefit of the doubt that you either know nothing about the Healthcare System and all of the extremally varied roles that make up that system OR that you live in a country that's Healthcare System is dramatically different than it is in my country. Which is Canada.
Working in a healthcare field does not automatically mean you have work in scrubs and only scrubs. Are there tons of job where its mandatory to wear them? Yeah, there is. But there's also tons of jobs where you don't have to wear them.
For Example:
Physical Therapy, Occupational Therapy, Speech and Language Pathologist, Recreation Therapy, Psychiatrist, Psychologist, Play Therapist, Case Workers, Outreach Workers, Grief Counselors, Addictions Councilors, Unit Clerk. I could go no, but I won't.
Its also relatively common for places such as where I work try to avoid using scrubs as much as possible. I work in an Adult Supportive Living Unit and so the people live there, its their home and I want it to feel like a home. So we do our best to make things feel as non-clinical as possible. This is the case with LOTS of places, such as (adult or teen) Group Homes, Rehabilitation Centers, Adult Day Programs, Homecare Services, Outreach Programs.
