GFL Environmental complaint: Sexual harassment

I would like to file a complaint against my former supervisor. I was laid off yesterday without warning and was told to go home. Myself and 5 others. I feel the reason I was laid off was because I refused my supervisors sexual advances. He called me sweetie on several occasions, touched me in my hip and grabbed me by the sweater, told me I had a nice body, asked me out to dinner, and always asked me to hang out. I told him once that I would not sleep with him because he made a comment saying I’m slow and ill ge fired and I said really and he said we’ll see how Saturday night goes. He asked me repeatedly to hang out so I said yes and after he said that I realized he wanted to have a sexual relationship. I felt extremely uncomfortable. I put up with way too much because I needed the job. I would like to make sure this doesn’t ever happen to anyone else. His name is Parth Rao.
