Templeogue College, an all-boys secondary school, has been at the centre of grievances aired at the Workplace Relations Commission regarding a range of issues.

Among them, last month two dozen teachers raised concerns about a “non-inclusive culture” regarding LGBT issues and the taking down of a Pride flag in the school canteen.

A recent controversy over the handling of a rainbow flag raised “deep value conflict concerns” and words like “bullying, victimisation, gaslighting” have been used on all sides.

The mediator’s report includes a number of recommendations, including the creation of a “charter for shared future” and facilitated sessions to deal with challenging issues.

In light of the flag controversy, it says there is an “urgent” need to clearly articulate the values and approach of the school with the Spiritans, board and school community.
