I have been working in the HR department of my company for a number of years. Would a course of post-grad certificates in human resources help me progress to managerial level?
Certification programs will help give you an insight and rather concentrated tuition in a particular area or field within the area of Human Resources. If you do not have any formal education in Human Resources, it may be more prudent to undertake a more comprehensive program; alternatively undertake a number of certification programs. This should demonstrate to your employer that you have more than a passing interest in HR.
