The keyword here is volunteering. If the person has so much passion and zeal to do more than they get paid for, why stop them?The job description of every staff Is spelled out the moment he gets a job in any company. This is usually directly proportional to the pay he receives and his certifications. However, is it appropriate for any staff in any business or company to be working more than he gets paid. Can he volunteer to do more that what was designed for him to do?
Most employees now even work less than they get paid for, so having the opposite should be appreciated.
