I've been working as a complaint handler for an investment company for about six months now, and I'm really struggling. I left an easier call center job for this position, hoping for better pay, but it's been overwhelming. I'm constantly working outside my contracted hours just to keep up, and the stress has started to take a toll on my mental health. During my first one-on-one with my manager, I actually cried when we discussed my progress. I was told I need to handle around one case per day, but despite all the extra hours I'm putting in, I often can't meet that target. Some days are better than others, but I feel like I'm just treading water. I've had three breakdowns already due to the stress, and I'm starting to wonder if this job is sustainable for me in the long run. I'm at a point where I'm questioning whether I should keep pushing through or start looking for something else. At what point do you know a job isn't the right fit anymore?
