Why are managers reluctant in a budget setting?

Managers may be reluctant in a budget setting due to several factors, including fear of accountability for overspending, concerns about resource allocation impacting their team's performance, and the pressure to meet unrealistic targets. Additionally, the budgeting process can be time-consuming and may require compromises that could limit their operational flexibility. This reluctance can stem from a desire to maintain control over their departments and ensure that their strategic goals are not undermined by rigid financial constraints.
