Dear Madam,
Training keeps happening in a working organization. The learning may happen in structured manner or otherwise, the learning may be different. Not training an employee hurts the organization first.
The care has to be taken in selecting the right people, training, hand-holding them, enabling them to perform, achieve and be acknowledged. The chances of attrition comes down. There are few still, who would like to leave, no issues, the organization is better off without such people, who would leave despite being treated well.
Thank you for raising an essential topic.
