Can't speak for higher levels, but if you're looking at grade 5 coordinator/officer roles:
-Your daily work will hold the organisation together but you will never be recognised or valued for it (new coordinator roles are offering pay ranges lower than when I started)
-Bad management = false urgency. You'll do a lot of work and be told it's urgent, before it's scrapped and never sees the light of day again
-High turnover rate is depressing
-Love of hierarchy, paternalistic approach and incompetence at higher levels means leadership is severely lacking. The place would probably run better with no one in place (see 100% turnover in the business development and research teams and complete loss of the global team)
-No development. There's an opaque progression policy and lack of consistency on how performance is judged. You will not move up based on how well you perform
-Many new roles are being created without normal recruitment processes (director became COO; CIO left and wasn't replaced; director became Chief of Staff, a role that never existed before)
-CEO has terrible communication skills
-HR struggle with the basics and complying with the law
-Cult energy
