Why managers are reluctant to spare their key employees for training and retraining?

Managers often hesitate to spare key employees for training and retraining due to concerns about productivity loss during the absence. They may fear that the investment in training won't yield immediate returns or that the employee may leave the organization after acquiring new skills. Additionally, there can be a perception that training is a distraction from urgent tasks, leading managers to prioritize short-term results over long-term development. Ultimately, this reluctance stems from balancing immediate operational needs with the potential benefits of employee growth.
