As a first year administrator, I've come to terms with the fact that no matter how hard I work, I'll never be able to please 100% of my staff. I had to have a difficult conversation with a teacher recently. I ended the conversation with the following sentences: "We have to do what's best for our kids. Are you asking me to do what's easier for YOU? Keep in mind that what's most convenient for US isn't always in the best interest of our students!" As per usual, I was very calm and professional. I think I got my point across, though.
