When I was teaching I never thought I could become an ATR. The 2005 contract seemed like a win-win and most teachers trusted the union. At the time my chapter leader said the seniority clause really didn't mean anything - unless you wanted to change schools and bump someone. (Most of us wanted to stay in the school we were in until retirement.) He went on to further explain it would stop someone from bumping us. No one imagined school closings and the creation of the dreaded beast "The ATR". As time went on the number of school closings increased, as did the number of ATRs.
Today many teachers are deathly afraid of becoming an ATR, partially because it's inevitable for experienced teachers. I now know many ATRs. Almost all are over 40 and professional individuals. (The stereotypes that abound are disturbing , especially when it comes from our union and fellow teachers.) Depending on your teaching background, some will have a much more difficult time than others.
Everything is taken away from you, except the pay check. You will have no routine. You won't know the kids, teachers, administrators, building, or neighborhood. You will spend a lot of money in parking garages or on tickets. You will have a new cold every time you change schools, because of the different populations and stress. You will have to carry everything with you- coat, bag, food, etc.. You will start at 9 in one school, 7:35 at another. If you had a miserable time in the past, this may not be so bad. If you had a great time teaching, this will be hard on you. How to survive?
Try to have a positive attitude. Try to exercise more, preferably before work. Watch yourself for depression and addictions ( shopping, overeating, gambling, and any of the more illicit ones). I have several friends who have become seriously ill and quit. Dress in layers - some schools are 90 degrees, others 40. Carry hand sanitizer and earplugs. (Yes, believe it or not, these rooms can get so loud your hearing will be in danger.) Carry some generic class work. Expect no help from the UFT and you won't be disappointed. Pick your battles, because you may win the battle and lose the war. Most importantly- don't lose your head.
