Dear Anita,
If you wish to enter into HR field then you need to start working in HR department. You will learn lot about HR when you actually get into that department.
Your past should not be a problem. In fact it will support you. Being adminstrator, you are HR professional partially. To make sure that everything runs smooth, administrator has involve personally. This quality will help you in your future HR career.
Whether you become HR Manager or any other manager, you need to learn managerial skills. Keeping in mind requirements of the people of your category, I have devised a training programme titled "Secretaryship to Managership". Since the word secretary is used, it should not be construed as it is strictly for secretaries. It is suitable for front office staffs, admin executives, secretaries, security etc. One training company has agreed to market this programme. Wait for the further details.
Please confirm you are from what city and your e-mail ID and we will include you in the appropriate mailing list.
Ok...
