New 'Kid' on the block in a business

I can relate to what you are going through. I agree, quite often it has to do with the natural resistance to change. People get comfortable in the status quo and the thought of having that situation altered many individuals see as personal attack, which doesn't quite make sense but that is how it is very often.  From my personal experience, some people felt threatened by my arrival- being the fresh blood full of ideas and wanting to improve many facets of the business. Especially if these individuals are of a certain rank or position and the possibility that you might question their authority of disprove their strategies and tactics, makes you a big threat.
