This is California.

I worked there for nearly 2 years.
For the last year, I was a keyholder and opened and closed 5 days a week.
I was never late and never called in sick.

I had an argument with a coworker.
Names were called on both sides.

I was fired the next day.
She continues to work there.
She is 18, I am 47.

Denial letter from E.D.D. states that I was discharged because you spoke to a coworker in an abusive or profane manner.

Wrongful termination?

She is the owner's best friends daughter.
The owner and I are still friendly.

Of course, I am going to appeal.
Should I bring up the fact of the owner/friend/daughter relationship in the appeal?
Does it make a difference?

Is having an argument with a coworker willful misconduct?

Any advice?
