One of the most important aspects of a good business or company is one that supports each other. Not just with moral support but when issues come up that need to be taken care of. A good business has people that aren’t afraid to step in when and where it’s needed. Which I’ve learned first hand starting my own business. It doesn’t matter if its part of your job or your problem; if you can fix it, take care of it. Don’t worry about someone getting upset you did their job. Think of it as a a bomb that needs to be taken care of now before it screws up the whole team. You’re more likely to upset people for doing nothing then by doing something. 

That’s something I’m aware of when looking for people to work with. The people who stand out are not the ones that just do their job and then call it done but someone who’s not afraid to jump in and help when it’s needed.
