4106 - Generally speaking, it is appropriate to offer a Tanya class for teachers in the Reshet

Only if they choose to join voluntarily, without any pressure or implication. In such matters, it's important that their livelihood from the Reshet is not connected to their participation in learning Tanya. Additionally, they should have the freedom to pursue the subject that they desire. https://www.torahrecordings.com/rebbe/igroskodesh/012/005/4106
