I can only speak for the major I did - a lot depends on what major you want to do as whilst there are common units, the majors can be pretty different.
I did the Human Resource Management and Industrial Relations major.
Whilst a few units in the first year were a bit tedious, especially in comparison with the law subjects, the latter years were really enjoyable.
It's a great course for critical thinking, especially in the third year subjects. It's really varied - covers a heap of different areas so it opens up a lot of work avenues.
Whilst of course there were a few less than great teachers, most i had were awesome - if you do end up doing anything in the School of Management and you have a choice, take classes run by Louise Ingersoll and Meg Smith and Nadine Campbell cause they're all really great teachers.
It's a good course to compliment law if you want to work in a Union, Employment association or other body in law or otherwise cause it gives you the background for those areas. It's also a good course if you want to practise in employment or OHS or other work related/business related law.
If not - the general knowledge gives you good skills for general application in work whether you go on to be a manager or not - gives you an understanding of managing people, how HR in firms functions and what they base things on (allowing you to rort the system for your advantage
lol) etc
