Workplace bullying on my autistic aunt

I'm at a loss. My aunt, a very loving, kind, hardworking, and generous autistic woman, (age 55) is getting constantly bullied at her workplace. She works at a thrift store in California. The pay is already quite low and she actually walks to work. She needs the pay to live and there's not much out there for her work-wise. She's applied to several other jobs.

Even the manager bullies her, and HR is no help.

She's bullied for several things: just being different, overdressed, overly early, etc. nothing that's grounds to be mistreated on a daily basis for 10 months . It's just so sad. The job is already quite demeaning and they further emotionally abuse her. Are there any resources, or something we can do outside of hiring an attorney? Myself and my family are outside of the state and can't help besides just supportive phone calls.
