qqtwizzy's journey

I’ve been working at my current company in a sales role for a few years now, initially hired full-time but transitioned to part-time to pursue my college education. I’m based in British Columbia, Canada, and I’ve consistently been a high performer, meeting most of my key performance indicators. Unfortunately, my direct manager, Ann, has never been supportive and has shown favoritism towards other employees. After experiencing unfair treatment, I reported some incidents to HR and even filed a formal complaint, but it only seemed to escalate Ann's hostility towards me. As I completed my studies, I decided to apply for an internal promotion that I was excited about. The vendor for the account I would manage expressed a strong interest in working with me, which added to my confidence. When I applied, Ann was out of the office, so I spoke with her boss, Ken, who mentioned that I could be considered for the role if I completed a specific task. I successfully completed the task and received positive feedback, including from Ann. However, when I finally connected with Ann after her return, she dismissed my efforts and implied that I wasn’t ready for the promotion without providing any constructive feedback. I tried to ask for clarity, but she avoided giving me any specific reasons. I later spoke with Ken, who acknowledged my growth and encouraged me to keep working hard, but it felt like he was aware of Ann's bias. I’m feeling incredibly frustrated and humiliated by this situation. I know I’m qualified for the position based on my sales performance and skills, and to add to my dilemma, I have an offer from another company. However, I really value the benefits and pay at my current job. I’m at a crossroads and unsure of how to proceed.
