This specific job taught me how to be in charge of others and how to take control and handle situations. The pool manager must be CPR and First Aid Certified as well as hold a Pool Operators license. As the manager I had to be alert and make sure all patrons were safe at the pool as well as my guards. Water chemicals must be tested hourly and maintained at the appropriate levels; if at inappropriate levels, must fix immediately to ensure pool safety. I had to keep a professional attitude throughout the day no matter what circumstance. The most important aspect of being a lifeguard, assistant manager or manager is your ability to react quickly and efficiently.
