please give me feedback on my thank you letter

"Dear Managers & Leads,
I wanted to express my appreciation and thanks for the wonderful job, positive atmosphere and amazing support each of you have given me in the first month and a half that I have been here. Specifically, the leads that I have had first had contact with have been very supportive, especially with accommodating my hearing issues. They have not expressed frustration or disapproval for the extra work they might have due to my hearing issue, on the contrary, they have be very positive and even offered great suggestions on how to work around it. They have made sure that I have been well stocked while at a cart. They have taken the time to come check on me, even way out at the churro cart. They have been patient and kind when I make mistakes, and have answered many, many of my questions even if it was the 10th time I asked. Each of you has made this job fun, enjoyable and something I look forward to each day that I come in. I truly appreciate you!"
