You must allocate your human and non-human resources efficiently. And in order to inspire staff, employers must first earn their trust and respect. If you make a commitment to your employees or customers, you need to follow through on that commitment. Employers should accept responsibility for mistakes and apologize when appropriate. Your leadership will command the trust and respect of your employees.
Money is a perfect example.
To some, money is a strong motivating factor, while others would prefer time off. Keep in mind that today's diverse workforce will require diverse motivation techniques. It is probably all of the above and more. Try to include employees in setting goals and developing work schedules. If you can reach a consensus on what to do and how to do it, your motivating task becomes much easier.
