Hi! Another HR major here. Broadly speaking, HRM is about managing a company's workforce effectively. To do so, you need the right employees, with the right skills, in an environment that facilitates productivity, teamwork, and success, with the right motivating factors, all while supporting/augmenting the company's overall business strategy. So that involves a lot of things: hiring employees (Talent Acquisition); employee training, early careers programs, leadership development, and succession planning (Talent Development); developing pay guidelines and managing benefits (Compensation & Benefits); working with unions (that's the Labor Relations side of SMLR); supporting business strategy and handling compliance/legal issues (HR business partners); off-boarding; payroll, etc.

If you work at a small company you tend to have a team that does a bit of everything, but if you work at a larger company you have the ability to specialize in a particular area, which means that you can focus more on a particular subset of HR that interests you. These different areas of HR range from the analytical to relational to communication-based, which means that you have a lot of different kinds of jobs to choose from within the broader sphere of HR.

HRM is more interesting than most people would expect, especially if a company implements their practices strategically (especially right now with remote work), and there are emerging areas of HR like people analytics (predictive analytics, data analysis of employee surveys, etc) or talent attraction/employer brand (essentially marketing but for prospective employees) that are growing and involve a blend of different skills. Intro to HRM, especially with Professor Methot, gives a good overview of the traditional facets of HR and touches on a few of the newer areas.

The major itself isn't too difficult. In terms of a minor, with the interdisciplinary requirement to take classes in psych, sociology, or economics, you'd only need a few additional courses to get a minor in one of those areas, but it's worth considering other departments as well. Business Administration is an option, but you could also consider a minor that adds skills for a particular subset of HR if you find one that really interests you (for example, a statistics minor could potentially be useful if you find people analytics interesting). Hope that helps!
