I have been working as a Security Guard for the last 10 years. During these years, many people asked me what is involved my job as a Security Guard on a day by day basis. Here is a snapshot of my typical day as a Security Guard. Beginning the shift – Reviewing shift notes At the beginning of every shift, I will review the shift notes of the Security Guard who was on duty before me. This will give me a good idea of what issues happened before my shift and any pending issues to be closed to be watched for etc.
