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. Although some employees are exempt, most are not.
The PhD in social work is strictly for research. You do not get more clinical training and thus the MSW is the terminal degree for professional practice. A social work PhD will not have any more clinical training than an MSW.
For an entry-level job, you will need at least a bachelor's degree in social work (BSW), but you may be able to get a job with a degree in psychology or sociology. Some jobs require a Master's Degree in Social Work (MSW), and if you want a career as a clinical social worker, this advanced degree is required.
