I recently started a new job as a [specific role] at [current company] just 7 days ago. I took this position after interviewing with multiple companies and receiving an offer on the spot since I wasn't employed at the time. However, I just got a call back from another company I interviewed with, and they've offered me a position with over $50k more per year, along with a company gas card and additional benefits that my current job lacks. I really like my new boss and the team, but the pay difference is significant, and the new role comes with higher responsibilities that I believe I can handle. I’m feeling conflicted about how to approach my current employer since I've only been here for a week. I know I need to take the new job for my financial well-being, but I feel bad about leaving so soon, especially since I have a good rapport with my boss. I’m considering how to communicate my decision. Some advice I’ve received suggests being honest about the unexpected offer and thanking my boss for the opportunity, but I’m unsure if I should offer a two-week notice or just leave immediately. I feel guilty about the situation, but I know I need to do what’s best for my career.
