Master's Degree in Social Work is required for licensing in the US (LCSW). To teach at a community college it's generally required to have a Master's degree as well.

"useful" is in the eye of the beholder. I would expect a company hiring manager to put a candidate with a Master's degree higher on the pile than those with high school or Bachelor's degrees, too.

It’s a bit of a mixed bag. If the degree becomes meaningless than the hiring manager may apply skepticism to why someone would need that degree.
