Considerations. If you have not filed a W-4 with your employer showing that you are exempt from federal tax withholding, the payroll department might have made an error. Check with your employer or someone in the payroll department as soon as possible to correct the error.f your employer shows you as exempt from federal taxes, it means that he is not withholding taxes from your paycheck.

The usual job requirement for a medical social worker is a Master of Social Work (MSW) degree. Some jobs may be available to social workers who only have a Bachelor of Social Work (BSW), but these jobs are usually lower-level assistant positions. Master's degree programs in social work usually last two years and include a practicum or an internship that may range from 400 to more than 1,400 clock hours.
