Ex Boyfriend Demanding Sexual Favors In The Workplace

I (22F location: Missouri) need help understanding my legal options.

I’ve been dealing with my ex who got me a job in sales. On top of being the top seller for the company, and us being around each other frequently our supervisor assigned him to train me. Now after a breakup, my ex has been coercing me into sexual acts in exchange for job training and help. He told me I needed to sleep with him for him to train me or assist me with commissions. Out of desperation—after he convinced me to quit my stable job—I initially agreed, but now he’s using this to manipulate and threaten me.

When I try to cut off contact, he messages me from other platforms, saying he’ll help me “no strings attached,” only to later demand sex again if I’m not “polite enough.” He’s told me if I don’t comply, I’ll be homeless and he’ll take my pets. He’s also reached out to my friends trying to bribe them into getting me to comply.

Now, because I’ve refused to be exploited, he’s refusing to help me finish a roofing job for my elderly family member, even though the work is mostly done and we’re just waiting on insurance. He won’t answer questions or help me with the customer, and I’m scared this will jeopardize the job and my income. I’ve told my supervisor about it, and was told he would call me about this matter but I haven’t heard back.

I just wanted to learn and do my job. This situation is causing me extreme distress. What can I do legally about this? Can I report him? Is this sexual harassment, coercion, or something else under the law?
