Social work and business administration?

[CoachT]

It's not only possible but very common. Many (maybe most) MBA students don't have a business administration undergrad.

Consider whether you might rather do an MHA (Master of Health Administration), MPA (Master of Public Administration), or MPH (Master of Public Health) though - these would be more useful for a social worker and would deal with the world that social workers work in more than will business administration. If you're wanting to advance in the world of social services management - any of these three might serve you better than an MBA. An MSW (Master of Social Work) is a good advanced degree for social workers too.

MBA types tend to be very 'facts and figures' people whereas social work types tend to be 'those emotional people' who make decisions based on feelings and concern for others. Neither is better than the other - we need both. But putting someone in an environment that is opposite of their style often creates self-conflict.

If, ultimately, you'd like to work in business (and not in social services) then that bachelor's degree in social work might get in your way a little. A bachelor's in business, accounting, finance, economics, marketing, etc... is better for preparing business people - a bachelor's in social work is for creating social workers. ☺

The social sciences of business are human resources (especially I/O Psych), communication (biz comms including marketing and advertising), and economics - you might want to look at those as well for an undergrad if you lean in that direction.
