If I have more seniority than another employee and request a shift change but am denied but the other employee with less seniorty gets the shift I wanted. Is it fair?

It may not seem fair, especially if your seniority typically implies priority in scheduling decisions. However, factors such as business needs, employee performance, or specific skills required for the shift might also play a role in the decision. It's important to communicate with your supervisor to understand the reasoning behind the shift allocation. Fairness in the workplace can be subjective and often depends on the context and policies in place.
