If you need to read something like this, consider it a mildly bad sign.<p>If you think this transactionally, it may actively hurt your ability to build these relationships.<p>Simply be nice, be on time, work hard. Treat everyone, boss, colleague or subordinate with high degree of respect. Remember that they are human beings and have families, and respect that. Consider everyone in your company as a member of a team working for a common goal, and presume positive intent. Treat competitors and vendors with respect and act ethically. Just have good manners and empathy, really. This is much better because it works universally, not just in professional relationships.
