Your co-worker terry is dealing with a lot lately. usually, he is a productive member of your team, but lately, he's been ill-tempered and even rude to you and the rest of your team. you know that terry's supervisor scolded him for poor work habits and he got a speeding ticket last week. he also seems worried that he might be fired. you're sympathetic, but his attitude is causing the rest of your team to suffer in terms of morale and productivity. how would you approach terry about his negative attitude in a positive and non-aggressive way?
