People will stay because of you, or in spite of you
As the saying goes, "people quit people".
So that begs the question, are people staying because of you, or in spite of you. Everyday we have the opportunity to affect people positively in their work environment, or negatively. You can also have no effect on them at all, but no one stays because of the person who doesn't talk to them.
Be a joy to work with, put a smile on people's face. You'll spend 40 hours a week with these people. Give without receiving, encourage without belittling. Be a reason someone will stay, don't be the reason someone is okay with leaving.
And for goodness' sake, don't ignore people.
