I just started a new job at a preschool and i already feel like the dynamics between me and my coteacher are going to be difficult. Shes been here for 17yrs and is currently in school to get her certification to teach. Her last co teacher of 4 to 8 years recently left. When i came in she wouldnt let me help set up the room because she already had everything planned out. I figured this wasnt a big deal because shes had all summer to plan and i came in 3 days before. But on openhouse she wouldnt really let me talk to the parents and when i tried she took over. Shed also tell the parents that she left at a certain time (an hour before me) so if they had any questions about their kid they could email her. Even though they could also just talk to me because Id be there still. But i didnt inturpt her but looking back i should have said that. I eventually gave up trying and started playing with the kids. But i feel like doing that discredited me as a teacher? Or is it still ok because they saw me interacting with the kids? Tomorrows the first day with the kids and Im nervous because shes teaching the first two weeks and I know shes going to take over because we havent discussed routines or expectations or what were going to do and she still has the schedule posted with her old coteachers name. Im worried she wont like me because shed rather have the old coteacher. It doesnt help that i have a very submissive personality. How should I handle this?
