Underemployed Workers Can Find Full-time Work.
Underemployed workers normally come from those who have part-time work taken until a full time position is available.  Or the employee has been downsized on the job so that the hours worked and position available no longer pay the bills.
The impetus to change that situation will have to come from the employee.  A struggling company or low salary level company will normally not be able to help you. Therefore, the search for a full-time, well paying job will have to be sought where the need matches your ability to solve their problems. 
Career Focus Workshops provide tools to locate those jobs while allowing you to maintain the part-time jobs which pay some of your bills. 
The Workshops are conducted after business hours so that you can maintain the part-time job.
