After seeing your post, one can come to the conclusion that you are very confident in HR. Nowadays, certificates are just the entry passes to attend an interview. As per my knowledge, many companies prefer experience rather than qualifications.
Suggestions for Career Advancement in HR
I suggest you complete a part-time or full-time MBA from a well-recognized university or B-school while continuing in your current position and company. Once you obtain your MBA degree, you can negotiate with recruiters/HRs regarding position and salary. Alternatively, you can pursue a certified course in training, performance appraisal, or any other HR-related topic to gain real-time experience. Companies will be more likely to hire you if you are certified in any HR course, given your 10 years of experience in administration and 2 years in HR.
Wishing you a bright future ahead.
