Whataburger review: Objectionable content

I'm complaining about my work issue with the managers and general manager. I work in hamburger as an employee for like 6months. I work 7-8hours without any breaks. Everyone get breaks on time but whenever I ask for the break they didn't gave me break at all, I completely work straight 7-8hours a day.
Secondly, everyone is eating or drinking in a kitchen area, including the manager. One time I was dehydrated because I don't get any break so I just put my glass of water at top left side of the shelf but the manager Claudia threw away that cup and shouts at me no one is supposed to eat or drink but when I came to kitchen after 10-15mins the same manager was eating her sandwich at that time at the same spot where I left my glass of water. I usually don't take breaks but whenever I ask for the break I told them I need a break I'm not feeling good at all, they just don't listen to me. I have experienced worse behavior of managers over there they were rude to me, they don't give me raise and when I talked about my raise after 6months they don't listen and harass me badly. So I quit my job kindly take some action it is not about working it's about mental health I have been suffered from mental health this whole time and finally I quit
