Today, I received a job offer for a new position as a Food Safety and Quality Manager with a salary of $107,500 plus a 13% annual bonus. This is a significant step up from my current role as Lab Director and Quality Assurance Officer at a small environmental company where I've worked for the past eight years. Despite my contributions, including improving procedures and obtaining certifications that generate substantial revenue, I feel drastically undercompensated with a salary of $85,000 and minimal benefits. I've been struggling with the lack of work-life balance, working 10-11 hour days, and feeling guilty about taking time off. My current employer has a history of being hostile towards employees who leave, which adds to my anxiety about the transition. I'm genuinely fond of my colleagues and the family atmosphere, but I know I'm worth more and need to prioritize my career and well-being. Now, I’m preparing for the difficult conversation with my current employer about my resignation. I’m nervous about how they will react, especially since I would be leaving them without a qualified lab director. I want to approach this conversation professionally but am unsure how to stand my ground without feeling guilty. Any advice on how to navigate this situation would be greatly appreciated.
