Employee Exploitation: The Harsh Reality of Corporate Culture

Let me show you something, this is how these companies are treating their employees even in a full time remote role, they think if they hire someone and give them salary they can make them do whatever they want. One of my friends is working in some MNC and they are pushing their work hours everyday single day like 5-6 hours like its no big deal that too with no compensation/flexi leaves, one day they sent this link of Google meet 11:30 am to 5:30 am (18 hours) and then they starting doing this everyday, its like we were practically living at work, with bosses expecting them to pull 18-hours shifts like it's no big deal. And when he finally spoke up about it, they accused him of not being flexible enough. So, when the project was finished they laid him off by saying that he is not flexible n all, How can anyone flexible of working 18 or 15 or 12 hours. This kind of toxicity is happening even in big companies. Remote role doesn't mean that you will sit on my head , make me join some 18 hour meet link and then do the tasks while being in the meeting so that the PM can interrupt me whenever he feels like it with his idiotic comment of: "is it done"?
