Starbucks is dealing with disruptions to its barista payroll and scheduling after a ransomware attack on Blue Yonder, a software supplier. The attack began late last week and affected Starbucks' ability to track hours and manage employee schedules. While customer service remains unaffected, the company currently pays employees based on scheduled shifts, which could lead to overpayments or underpayments. Starbucks emphasized that all workers will be paid accurately for their hours worked.
