Today’s best managers know that employee regrets can influence employee behaviors over time. Employees may feel guilty about how they spent their time off and employees may regret the choices that they made about their leisure time. Employees who completely take time off from work to relax tend to regret not working through their breaks, but their regret fades quickly over time. However, employees who work through their breaks tend to regret doing so over time, but they also have ever-growing feelings of resentment about having missed out during their break. Help your employees lessen their feelings of resentment and regret no matter what choices they make.
