Feeling Like Being at Work is Intolerable?

My employer got mugged by a Latino man and lately he has been openly hostile to me. I am Latino, but I have worked for him for 2 years, so I do not know why he is taking it out on me. Is this legal?

If a reasonable person would feel compelled to resign because their employer intentionally caused objectively intolerable working conditions or knowingly allowed them to exist.
