Business partnerships are just like any important interpersonal relationship - they require attention and care to thrive. Unfortunately, many partners can fall into traps that sour the relationship and even create a toxic work environment. This can lead to costly disputes and dissolution of the partnership.
When you are going into business, you may decide that pooling resources and talent with someone else or multiple other people is the best route. This may also feel less risky as you are not jumping into the venture by yourself.
