When people in office support jobs do have a bachelor’s degree, it is most likely to be in business (http://www.census.gov/dataviz/visualizations/stem/stem-html/ - choose Non-STEM tab & put your cursor on ‘Office support’). People with degrees in Business Management are sometimes seen working as administrative assistants and the like (http://www.payscale.com/research/US/Degree=Bachelor_of_Science_(BS_%2f_BSc)%2c_Business_Management/Salary), but it does not appear that people with accounting degrees work to any significant extent as mere administrative assistants (http://www.payscale.com/research/US/Degree=Bachelor_of_Accountancy_(BAcc)/Salary).
