Am I wrong for leaving?

Edit: Got Fired today. Fuking manager snatched away my quitting moment 🥲 but I appreciate all my colleagues reaching out after hearing the news. Felt good my colleagues valued my work. Felt good

Hey community,

I'm reaching out for some perspective because I'm too close to the situation to make an objective decision.

About eight months ago, I transitioned from a retail job to a corporate role at the same company. Since then, the company has undergone significant changes, and our team is entirely new. Initially, I was overloaded with tasks, including:

1. Learning two new HR systems.
2. Creating scripts to print letters depending on type of employee movement for 20,000 employees.
3. Developing payroll reports from scratch with no training.
4. Creating guides for various processes.
5. Handling 20 cases per day.
6. Answering phone queries.

Despite receiving no training, I managed to tackle all these tasks. I consistently volunteered for extra tasks and helped my teammates, all for only $100-$200 more per week than my retail job.

Recently, my manager criticized my performance, even though I have the second-highest closed cases on the team. He mentioned negative feedback from his manager but provided no details. When I asked why I wasn't given a chance to correct my mistakes before raising concerns, he said this was my chance. I was taken aback by his approach. The next day, I took a day off, and my colleagues reached out, knowing my 1:1 meeting hadn't gone well. My manager also hinted that they don't see me around much, despite no explicit expectation to be in the office regularly. My team leader has acknowledged that I work past my working hours on some days. So everyone in my team knows how active I am.

I get paid very little, have done a lot for the company, and received no appreciation—only criticism. However, I have messages from various colleagues and even a senior leader complimenting my hard work. I even receive d two shout-outs (internal award system) acknowledging my hard work. These shoutouts are visible to everyone in the department.

My partner and colleagues are supportive and advised me to grow a thick skin and move on. But I’ve lost my passion for this job, I'm tired of my manager's treatment, and I feel underappreciated.

I’m considering quitting and returning to retail, where I had more freedom and my managers valued my work. I might need to dip into my savings until I find another job, but I'm not too worried about that. Should I just quit?
