write a formal email to my principal talking about: 
My preferences for next year, I would love to stay with my students, as I worked so hard with them and I will feel sad if I don't stay with them but not with the same team, I can't stay with the team as many times I said what is happening. 
I still remember while joining Trinity (as previous name), Mrs Yan, Mrs Joyce and Mrs Brenda told me that working with Lauren is difficult as she doesn't do anything and I need to keep telling her what to do, also Lauren mentioned that Miss YAn told her if the foreign teacher is quitting it is because of you. 
Since K1 I was telling her what she needs to do and 50% of things are not done, I need to keep repeating and reminding and to be honest that make me feel anxious and less energy, but I still chose to work with her in k2, but now to be honest after many things happened, I can't bear it anymore, most important ones are exit point (fashion show) as you notice I was doing everything and I gave each one their position and their mission they didn't do, so I found myself relocating from spot to another and assit the kids also, second one is the communiction, sometime I say something but she doen's deliver it as I said, for Chinese IEYC, I can count how many classes she held since K1, and when we started talking about organs I was strict and firm with her to be having CHinese IEYC as the topic is a bit difficult for the kids so they need it in Chinese also, I gave each one a group of kids they need to work on it, I started assessing their groups and no improvement then I found myself doing it by myself again, and the last ones triggered me is they throw the kids craft, any one or any responsible teacher will know which craft should be thrown and which should be kept and while I had my play group I gave them 2 things to do, rehearsal for the song which will take 20 minute and comeback and do the activity I already prepared they don’t need to do anything just watch the kids, then they only practised the song and the excuse was we didn’t have time,  
Sorry to make the email long, but I really feel I can't stand working with her anymore, I am tired of telling an adult, a responsible teacher, what they need to do, my students know what they need to do; I am tired of thinking about everything by my own, organising; I am tired of checking with them as a team and deciding all together; and, in reverse, I find myself not aware of anything. I am tired of asking them each time to get their groups and work with them, I don't feel happy coming to school, to be honest, because I feel like I am coming to tell others what to do and not teach kids. Also I wonder what is she doing on her laptop most of the time, Whenever I ask, the answer is educational bureau things, I asked her to manage her time many times, I do understand they need to do a lot but it doesn't mean you should be having your laptop 80% of your day time, I asked her many times then how the other chinese teachers are doing ? why they still have their time with kids and having their circle time together, I even asked her many times to talk to Jenny and check with her how she is doing the things and she can tell you what to do. 
I asked Jenny also and I told her what they are doing so we can divide the job I am responsible of phonics for example and you are responsible for maths, then she did a maths sheet once and same counting activity every day for that week then never happen again, then I told her again to do it but didn’t happen, teaching needs consistency, my team doesn’t have it, So I feel if I am not in the class nothing will be done, and yes during christmas holidays they supposed to do 3 activities, only one was done, when I comeback from holidays I was like why you didn’t do, no time as always, then I managed the time and we did. 
Our classroom is not decorated because I didn’t do it, and if I didn’t do something, it won’t be done, so it is too much for me to do everything by myself so I am just focusing on the kids learning, happiness and safety. 

I am a teacher who likes to do things right and in the right way that’s why I push myself and the kids too to become better and better but one hand will never clap. 

I would love and be happy to move with my kids, but it won't give me the excitement if I stay with the same team, I got my enough. 

I am writing to you just to let you know how I feel.
