Higher Management lives in a cocoon of privilege and as a result are arrogant, dismissive and careless. They are also completely lacking in self-awareness. Cult-like.
Annual Performance is generally judged based on other's perceptions of you and what you do, not the work you actually do. This means that your hours of toil on a project mean nothing if someone in a 'higher' role than you reports something negative about you; doesn't matter if it is true or not.
The organization does not practice the values they claim to preach: BC preaches diversity and inclusion but 90% of the higher management is white, male and British. Preach about the importance of mental health/work-life balance, but managers will expect 50-60 hour workweeks to prove your commitment.
Finally and by far the most frustrating; the lack of any serious accountability. Finger pointing and blame is commonplace. Serious mistakes never come with consequences for the person that made them; was personally told on multiple occasions that "the British Council" was accountable for clerical/accounting/financial/scheduling errors. Everyone is accountable so no one ended up being accountable.
