"It can always be difficult to disagree with someone who has been working at a company for longer than you have. You assume they have more knowledge and experience, and they likely have good reasons for taking that specific action. I have not disagreed with a supervisor, but I have had a situation when I have been frustrated with something a supervisor has done. After thinking through the situation, I still had questions, so I scheduled some time to sit down and speak with him. I was able to explain why I wanted to meet and ask my questions. After our meeting, I better understood the situation. Thankfully, my supervisor was not defensive. Had I immediately reacted and questioned him in front of others, there could have been a different result. It's important to spend time investing in working relationships as you are around these people for most of your day."
