Pros
Good support as an employee. As much as the 'group' is a drawcard: your clinical learning is still dependent on the practitioners within your individual practice. PD fund, weekly mentoring etc
Kontras
May make you squeamish if you are a completely sales adverse health practitioner. They didn't become the biggest Physio group in Australia without thinking about marketing, retention etc I looked into directorship and decided it wasn't for me - I think BIM is great as an employee, but tread with care and ask for facts+++ before going into directorship (I found senior management very keen to talk about growth, future, REVENUE etc without showing facts and figures - not good enough if your going to sink hundreds of thousands of dollars into opening a practice)
