Meetings are a waste of time. They are formal, they discuss things that all of the attendees already know, and in most cases, the content being shared could have been done with a simple group email. So why not have all discussions through emails? Because emails don’t help build rapport between the sender and the receiver. What does help people working together connect with one another is having a comfortable discussion over tea.
Let’s take 20 minutes
Taking around 20 minutes on a Sunday or Thursday, when all of the teachers and supervisors are available to talk about what they are working on, helps create camaraderie among the teachers, and gets them all on the same page. Discussions can be started by anyone, and the conversation can follow a clockwise or the alternative pattern. It is important to establish that this is not a show of how busy a teacher is, or if a teacher who isn’t working on much, doesn’t feel shamed by it.
Talk things through
Teachers can talk about who is working on what, how their tasks are going, and if anyone is facing any difficulties in doing something and needs help. This builds rapport between the 
teachers; it creates an environment that is welcoming but not informal either. Teaching is still a profession, and as such, a certain decorum needs to be kept; however, there’s a way that decorum can be relaxed but not taken away entirely. If done right, the teachers will be comfortable enough to ask for clarifications on things which they might be confused about, or announce that they don’t have that much work on a particular week, and are available to help another teacher.
Friendships are great, cliques aren’t
Friendships do form when people work together, and it’s important that they do; however, what is corrosive to a work environment are cliques. Usually forming based on not knowing someone enough, cliques are sufficiently toxic and to be handled with caution.
By having a group discussion, every teacher comes on a level playing field. There are no walls or barriers to hide behind, and one’s attitude towards another becomes clear enough. If the supervisor or a teacher sees that something is out of order, then they can make a note of it, and it can be addressed privately involving those concerned.
Talking comes naturally to most people. So it’s intuitive to have a group discussion once a week, where everyone takes a turn to talk things through. Solving problems, asking for or offering help, can all be done here, one just simply needs to be part of the discussion.
