In-service is mandatory, and all staff must attend at least 4 hours a month. 2 of these should be Company Inservice - those below- and the other 2 should be your home pool inservices.
Places of all in-services and meetings can be found online, or by asking your supervisor.
The ABP Website lists all company inservices for reference here: https://a-beautifulpools.com/lifeguard-staff-member-info/employee-resources/company-in-service-manager-meetings-and-events/.
