Today, I found out that my company decided to fire a colleague without any prior notice, and now my workload has significantly increased. We were informed that she was let go due to her repeated unavailability while working from home, as she often didn't respond to calls or messages for hours. Now, my responsibilities have expanded to cover her tasks along with another teammate, and it feels overwhelming. I can't help but think that they should have retained her since she was able to complete her work. It’s frustrating that there’s been no communication about whether they plan to hire someone to replace her. The job is complex and would require extensive training for a new hire, which could take months. Moreover, we’re not allowed to work overtime, and I feel that if we’re taking on additional responsibilities, we should be compensated for it. It worries me that if another team member leaves, we might be in a really tough position. I know the company views everyone as replaceable, but this situation seems unsustainable.
