She's observed all kinds of situations relating to water safety. This is made into an even worse situation when the offenders are either acquaintances of the staff member involved, or around the same age or slightly older. In all cases, being strict and being listened to isn't always easy. Since lifeguards deal with the public, and because they have to enforce strict rules, they must be both diplomatic and firm. The way they emphasize safety rules to adults is different than the way they convey rules to children.
Lifeguards also have to be good at communicating in other ways, too.
For instance, a lifeguard has to discuss with parents the progress their children are making in swimming classes. Lifeguards also communicate with their co-workers. Between lifeguards on shift, we communicate via hand signals to each other as well as passing along messages. They also have to communicate with the general public. With the public, we use our own PR methods as well as a public address system, used both for emergencies and messages to the public, or even game announcements.
