    Most contemporary organizations attempt to better serve demand by means of a wide array of flexible labor arrangements–including the use of on-demand or irregular schedules, part-time or temporary workers or the use of fluid teams. Understanding the effect of the use of these practices on worker or team performance is of primary importance. In fact, despite the operational flexibility they provide, these practices entail potential costs for the firm, due to limitations in the flexible use of human resources. The goal of this dissertation is to contribute to such understanding, building hypotheses on research in operations management and human resources domains and subsequently rigorously testing these hypotheses using secondary data from real organizations. The first essay introduces two metrics of on-demand schedule characteristics: idle unpaid time within the day and variability in the schedule across the weeks and measures their effect on employee absenteeism and patient dissatisfaction in a home healthcare setting. The second essay explores how the mix of subcontracted workers and permanent ones in project teams affects project performance in a high-tech engineering and manufacturing multinational. The third essay investigates how the allocation of the workforce during project execution affects its performance, by empirically exploring front-loading, or the allocation of more human resources in the beginning of the project. The overreaching findings of the dissertation is that besides their operational advantages, flexible labor arrangements can have multifaceted impacts on individual and team performance, and that such impacts can be both positive and negative, depending on the considered practice and various contingencies.
