My question involves labor and employment law for the state of: California
Recently I applied to a company that was offering paid training and a 1 yr contract. The company is headquartered in Utah but has offices and obviously operates in California. On the application it asks the question "have you ever had convictions that were expunged?" which I found out is illegal under section 7287.4(d) of the California Code of Regulations. The person who took my application in Utah called me up because he found out about that I have an expunged record and pressured me over and over to tell him what the convictions were for, I told him that I'm not obligated to disclose that under section 1203.4 and that he was violating state law by asking for this information, which he then told me I'm out of luck because "this is Utah not California" and subsequently denied my application. My question is does it matter if the headquarters is in Utah but violates the law in another state? What kind of case do I have against them and what are my options? I have opened a case with the DFEH, though I'm not sure what to expect from them. Also I should add that this company is 100% a private company, not a Government agency nor does it require a security clearance or the ability to travel out of the country where as I understand it I might not be protected by 1203.4 relief.
Any advice would be great thank you.
