Poor change management. So much has happened in recent months - year, and little has been done to mitigate that impact on operations, and daily communications, which always ends up impacting employees.
Pay gaps . . .
The weight of many systems and services falls on the shoulders of a few.
The large amount of bad management casts shade on the few great people.
Almost the whole company has left and been rehired in ~1 year
Just acquired by a massive mega corp.
