Will I be able to get a job with a major in "Behavior and Health"?

So for next year, I’m majoring in Behavior and Health as part of the “pre-occupational therapy” track. So basically, I’d graduate with my bachelor’s and then go onto graduate school hopefully still at Boston University, since its the #2 OT masters program in the country.

However, BU’s reputation for grade deflation has me terrified. If I have a poor GPA for undergrad, aren’t my chances of getting into the masters program destroyed? And if that happens, will I be able to get a job with a bachelors degree in “Behavior and Health”?

I’m honestly considering changing my major, maybe to something business related with more job security. But I also don’t want to give up on a job I’ve been considering for nearly three years, and which I based my whole college admissions process off of.

BU gave me a great deal with 41.4K off, mainly consisting of a grant and some loans. I like BU a lot better than my other options, it’s a good school, reasonably close to my home, and in a great college town. My other option is the 5.5 year masters program at UNH, and I’d be paying only 11k a year with all the money I got off. But I would rather go to BU, a better ranked school in a better location.

So would that major be viable in the job market?

Thanks
