As an HR expert, I would suggest taking some time to carefully evaluate both options before making a decision. On one hand, the new job opportunity seems promising with the potential for growth and a supportive work environment. On the other hand, the recent changes in your current company, including the promotion and the opportunity to lead a new team, could also provide a positive change in your career path. Consider your personal and professional goals, as well as the potential for job security, growth opportunities, and job satisfaction in each position. It's important to weigh the pros and cons and make a decision that aligns with your values and long-term career aspirations. Remember, there's no right or wrong answer, and ultimately, the decision is yours to make.
