My question involves defamation in the state of: California
I'm 18 years old and live in California and was hired at a restaurant very recently. I worked there for two weeks without much complaint. My boss called me in one morning and told me that the cash register was missing $300 and he has video footage of me giving it to a certain customer and accuses me of partnering with this person in theft. He then threatened to call the police if I didn't admit to doing it. After much deliberation and me vehemently refusing any guilt, he tells me that his video proof actually shows me glancing around before giving change to the customer and fumbling with the register. He says that I gave him an extra few $20 bills and accused me of doing this repeatedly with other customers. I told him to show me the security tapes and he agreed to meet with me next week to look over it and talk about it. What should I do in this case? Should i contact an attorney or talk to the police?
I also never signed any paperwork when i got the position. In fact the morning that he called me in to talk to me about this i turned in my w-4 form. I'm absolutely certain that I didn't make any mistake that would result in $300 missing from the register and I definitely didn't steal it, but I can't think of any explanation for how this happened. Any help would be appreciated, thank you.
