I'm currently doing the Bachelor of Business and Bachelor of Law at UTS and the handbook structure has us do the management subject in the first semester. I can tell you it's definitely the hardest D you will get (70% of the assessment marks comes down to 2 essays, one at 50% weighting, and you may think that essay writing is easy but the standards they mark at had my tutor give 2 D's out among his 2 management tutorials overall with about 30-40 in each class, and he said it was similar for most of the other tutors). I wouldn't suggest it as a major because like you said, it's employability is pretty drab. Do you know if you will end up doing the management subject in the near-future? Perhaps think about majors when you get a bit more experience with the subjects listed there. Don't want to end up picking a major you don't like hahaha
And like Brent012 was saying, the course structures for Business at uts are really well set out. Accounting, being absolutely notorious for having a ridiculously high fail rate and being difficult in general, I found to be really easy to learn just paying attention in lectures and doing the tutorial work as it was prescribed. And I'm even able to help out my friends at UNSW and USYD when they come to me for help with accounting. The same goes for economics. It's really well structured and simply doing the work in the tutorials each week and paying attention in the lecture gets you quite far. But I'm not sure about employability for economics majors because I never really intended on majoring in it so I haven't done the research. My friend has told me that the marketing subject is very enjoyable and quite easy to do well in.
