Final answer:
Bubfizz Soda Inc. is offering James a flexible work schedule, which is a benefit that allows him some discretion in planning his work hours to suit his personal needs.
Step-by-step explanation:
The benefit being provided by Bubfizz Soda Inc. when giving James the option to work for four nine-hour days instead of three twelve-hour days is a flexible work schedule. Flexible work schedules are employer-provided benefits that allow employees some choice in planning their workdays and work hours. This flexibility can contribute to better work-life balance, reduced work-family conflict, and can provide employees with options that better suit their personal lives and preferences. It does not directly relate to a higher pay rate, additional vacation days, or health insurance coverage.
