Conflict within a family

I am UAE national living in Ras al Khaimah 29 years old female. I have graduated in 2005 and because of my mom health I could not work or study as I kept travelling with mom for her treatment.

Last year mom passed away and I came back with my brother. He insults me and forces me to work as a servant at home. No phone, no job and even shoun that government gives me, he took all that month. He said no shoun had come last month. I know there is shoun, he bought a phone for me just to not araise complaint against him.

I want to do a job, he refused. All that years I ignored about my life but when I want he refused. Now he took my passport, ID, health card.

How can laws help me to get a job?
