Cameras at work in break room with self checkout for self vending machines 24 hour surveillance

At work they have a cameras in the breakroom, it's for self check out for food that they have on display. Obviously that should have been my first red flag not to talk bad about Anyone, in general if you don't have anything nic to say don't say it at all. And I should know better being an adult. Well this Tuesday I came to work and my coworker told me to becareful about this new coworker. Because she complained about me because I didn't clean underneath a bed because there was pee underneath the bed. Keep i did clean the bed underneath, the patient just pees on the floor a lot. Well she said I don't do a good job and told everyone in that area. She took pictues and sent to the manager, saying what I supposedly didn't clean was un called for, saying i only take out the trash. Well Tuesday rolls around and that's when my coworker told me that, that was what happend. And I got frusted because I did clean underneath the bed, I was being accused of something false. Well when my coworker told me I didn't say nice things about the new coworker, and the manger and the old manager. I called them dramatic, and they and they don't act right in the breakroom in spanish . I know I shouldn't have said it because who the hell am I too judge, i'm not. Well 2 hours later someone. Told me to watch what you say in the breakroom cause HR listens to the conversation cause they were shown a video where they called someone slow and got written up. My question is how long will it take for my job to show me the video. Write me up or fire me. I totally get why they would I don't blame them. I shouldn't have said anything negative. I should know better being an adult?
