To ask for additional responsibilities, start by compiling examples of your recent accomplishments and demonstrating how you've successfully handled your current role. Schedule a meeting with your manager, letting them know in advance that you'd like to discuss professional growth opportunities. In the meeting, express your interest in taking on new challenges to develop your skills and contribute more to the team. Suggest specific tasks, projects, or areas where you believe you can add value and explain why you’re well-suited for these additional responsibilities. Emphasizing how your growth aligns with team or company goals will show that you’re committed to mutual success, making your manager more likely to consider your request favorably.
