Skills acquisition and continuous learning are essential for the employee to do the job. Employers provide opportunity and training - employees must take control of their own career plans and education. Employees are expected to do more with less supe rvision. Job security and employability are now the employee's responsibility. The employer must provide some degree of flexibility.
Top employees demand it.
Work schedules are becoming more flexible. Employees are considered as business assets with just as much importance as customers or investors. This is a major conceptual problem for many traditional managers. If the employer does not offer that then the employee will leave. The best 'formula' is to match the employee's career goals to the company's goals.
