My question involves labor and employment law for the state of: WA

I received a call from my employer saying I was fired due to them not having enough work, I asked why I was being fired and not "laid off", she then said a $10bill was missing from the till and she thinks I might have taken it, I asked to speak with her about this in person, she said OK and hung up. I have since left several messages with both her and the owner and no one will return my calls or meet with me. Friends that work there told me she told them the tills were off by $90 that day and she SAW me take a $10bill.

I never took a dime from them and I figure I must have done something either inside or outside of work to make them not like me and that's why I was fired. To be honest I really don't care if they fired me simply for not liking me.

Is it legal for them to tell people that I was fired for stealing? This is a small town and I do not want them telling customers that I'm a theif. I was official fired because they didn't have enough work, NOT for suspect of stealing.
