When an employee's time is managed correctly, they are exceptionally productive.
It is the continued focus on time management that leads to high performance, less stress, and high morale. These are the top 5 problems in Time Management:

Being Busy
Employees get a adrenaline buzz from being busy.
The endless emails, the narrowly-met deadlines, 'saving the world' at the last minute.
Busy makes you feel important and sought-after. Busy also make you stressed.
"Busy" sounds like "thriving" or "fulfilled" or "successful".
"Getting things done" sounds like "boring", "monotonous" and "tiresome"
Busy employees are not effective employees. They are not focused on the high priority tasks. The're just.. busy...

Taking on Too Much
Most people find it hard saying "no" and then find themselves with too many commitments on their plate.
We believe we can do far more than we can, we overcommit, and then we stress out when we can't get everything done.
The overachiever insists on doing all of the work by themselves, because they can't trust anyone else to do it properly.
Trying to multitask by focusing on more than one task at a time results in doing both tasks poorly, usually with errors.

Failing to Manage Distractions
Emails, phone calls from customers, colleagues that need advice - distractions stop the steady flow of work that we acheive when we're 100 percent engaged in a task.
Self distractions also make you lose focus. Putting off tasks that you should be focusing on right now. Delaying tasks that should be done but you don't like to do.

Failing to Plan
Planning is essential to correct time management.
Defining task priorities, setting deadlines, deciding what's worth spending time on, focusing on the urgent tasks, setting key performance indicators, prioritizing tasks, effective scheduling of employee time.

Failing to Analyse
Evaluation of the time spent is critical in planning and scheduling.
Analytic technologies provide historical, current and predictive views of the employee's time.
Workforce time analytics are a key capability for organizations seeking a more proactive role in driving employee performance.
