If you don't
If you don't invest your time on people, you need to spend your money on people

If you don't invest money on nurturing people, you need to spend money on correcting their behavior

As a manager if you don't invest your time on getting feedback from your subordinates, you will spend your time on conducting exit interviews

If you don't invest your time on listening to your employees suggestions, you need to spend time
on listening to their grievances

If you don't invest time on listening to your employees ideas, you need to spend your money on hiring  consultants to generate ideas

If you don't invest time on one to one reviews, you will spend time on resolving conflicts

If you don't invest time on identifying the right candidate, you will spend money on looking out for new candidates

If you don't invest time on understanding employees needs, you will spend money on irrelevant employee engagement activities

If you don't invest time on communicating the organization vision, you will spend money on aligning the employees towards organization vision

Invest and reap returns, don't spend and regret
