I also agree with this. The way managers and directors express their direction promotes the team building within the department. I have experienced both sides of the coin and like you I do prefer the welcoming work culture. Even though all the companies I’ve worked for utilized an organizational matrix, it is really easy to feel left out on a day to day basis if the company has a poor culture. This is especially true if you are rotated into a competitive department. On the flip side making the best of a situation is a useful skill to have. Like you said, striking that balance of work and play would be ideal.
