Lifeguards are trained professionals typically employed at recreational swimming pools to ensure the safety of the public. Lifeguard job duties and responsibilities include advising swimmers of proper behavior, upholding safety regulations, handling emergency situations that require CPR or first aid, organizing pool activities, and assisting with pool maintenance. Depending on the position and career path, lifeguard requirements may also include administering swimming classes. In many cases, people work lifeguard jobs for the summer and are seasonally employed and work in-person and part-time, including weekends.
