Starbucks is a multibillion dollar corporation specializing in coffee and other beverages. They have issues with inconsistent scheduling and a lack of trained employees to cover sick shifts. The document proposes implementing on-call shifts to address these issues. On-call shifts would allow managers to call in more employees when anticipating busy shifts and prevent sending home employees when shifts are slow. This solution is quick, easy, effective, and free to implement. The only drawbacks are that on-call shifts do not guarantee against all staffing issues and require ensuring employees are called in as needed.
