I though immediately of "insularity".

https://www.ecorfan.org/collections/nayarit-2019/T4_Panorama... (page numbered 37):

However, Antúnez cited by Rodríguez (ibidem: 32) mentions the following disadvantages of collegial work: **"Isolation (cellularism, insularity or balkanization of teachers)**, rigid structures that dictate what has to be done, the formal structure, well determined and formalized does not guarantee collaboration, teachers give more importance to their role than other situations, school schedules, usually prevent meetings, teachers with passive behavior or hindering teamwork.

Sin embargo, Antúnez citado por Rodríguez (ibidem: 32) menciona las siguientes desventajas del trabajo colegiado: " Aislamiento
***(celularismo, insularidad o balcanización docente)***, las estructuras rígidas que dictan lo que se tiene que
hacer, la estructura formal, bien determinada y formalizada no garantiza la colaboración; los docentes
le dan más importancia a su función que a otras situaciones, los horarios escolares, por lo general,
impiden los encuentros, docentes con conductas pasivas u obstaculizadoras del trabajo en equipo, la
forma de proceder del directivo, la situación de inmunidad o impunidad que percibe el docente y por
último, la magnitud del centro escolar facilitara o dificultara el trabajo colegiado."

I've come across a term "balkanization" but I am not 100% convinced that in your case whether the term applies.

Lesson 6 Blog Part 2: Pros/Cons of Various School Cultures

In your view, what are the advantages and disadvantages of each of the following types of school cultures: individualistic, balkanized, contrived collegiality, and collaborative?
Individualistic:

Advantages: Teachers who work in isolation due to physical barriers present or due to personality tend to take more ownership of their work and develop strong, caring relationships with their students due to the fact that they are very much involved in the happenings of their classroom. Also, these teachers value privacy and working in an individualistic manner can prevent the teacher from being distracted by outside happenings (i.e. gossip at the school). Furthermore, these teachers tend to protect their time and energy for immediate instructional demands and this type of work style is seen as an adaptive strategy to the work environment of teaching. These teachers are autonomous. This type of teaching style is generally stereotyped as negative or due to their personality trait however research does not support this.



Disadvantages:

These teachers do not have the opportunity to receive praise or support from their colleagues. Also, when a teacher isolates herself, she may be blamed as a scapegoat who is resistant to change. Furthermore, when a teacher isolates herself consequently she will not feel like a member of the school "family" and may not feel the inter-connectedness of being a part of the school team. They are fragmented from other teachers and students within the school. A final negative point is that this style of teaching goes against the recent push for collaboration amongst teachers.



Balkanized:



Advantages:

A positive to this learning style is that the subgroup that is frequently collaborating together can communicate often with other colleagues of the same subject area; they can bounce ideas off of one another and plan together. There are opportunities for support.

Disadvantages:

The sub-groups within the school that define balkanization frequently become isolated from other groups. There is exclusivity to these groups and other teachers often cannot join the group once it is established. Another drawback is that teachers in these sub-groups cannot learn from teachers who have different backgrounds or who teach different areas. This limits their learning to solely from people who have very similar experiences/beliefs.

Once teachers are in their sub-group they usually stay there and do not network with teachers from other groups.



Contrived Collegiality:

Advantages:

This practice is in alignment with ideas about instructional leadership, transformative leadership, and shared governance practices. Another positive is that when collegial practices are in place, it is easier to implement a new curriculum (as all teachers are frequently meeting together) and it ensures a more centralized curriculum being presented within the school.

Collegial experiences provide teachers the opportunity to learn from one another. As a result of learning more things, a teacher may be more willing to experiment or take risks in the classroom because they feel that they are in a safe environment.

They are regularly scheduled, which is good for a teacher who needs weekly or monthly support from colleagues.



Disadvantages:

A drawback to this practice is that collegiality can take many different formats and unless leadership is well versed in this area and has a clear vision, purpose for these collegial experiences among the teachers, it could be implemented incorrectly.

Another negative aspect to this strategy is that teachers feel forced by administration to engage in collaborative experiences with peers and there is no ownership of buy-in on their part.

The scheduled meeting times may be inconvenient to some teachers.

Finally, it has been found that these sessions usually consist of short-term unit planning among teachers, which is on the intent- which is to discuss principles, ethics of practice.

Lots of preparation is involved- such as identifying norms for the group, setting a vision, facilitation to make sure that the collegial sessions are being carried out as it is intended to.
