But a plain vanilla psych major is perfectly fine for anything HR/Org related.
The “business specific” elements of organizational behavior, design, etc. can fit in a teacup. Psych- with a rigorous stats sequence- will serve her well. Everything in HR is moving quickly towards analytics, data, etc. so folks who have worked with large datasets, can use R, SAS, SPSS or similar are at a huge advantage vs. someone with an HR adjacent major who has focused more on the counseling side of things.
Even Employee Relations- probably the most “counseling” of the HR disciplines- has become much more analytical in the last ten years. Someone in senior management forwards you a massive spreadsheet and says “Can you tell us the three drivers of employee turnover over the last ten years?”. Or “Here’s the raw data on the last employee satisfaction survey (50,000 employees). What does it tell us?”
So any social science training with a rigorous analytical component is going to be key!
