(Senior) Management - from poorly trained individuals to persons being rude for the sake of it (not just my experience reflects this)
Lack of responsibility - just throwing the important decisions from one team to another taking months to end up with a decision.
Lack of compassion and transparency - in the process of making redundant 600 people.
Lack of accountability - I waited for 6 months the decision to be promoted, which was always postponed and in the end I was made redundant. Every time I was asking about it the manager of my team was blaming the senior manager, while the senior manager said he only heard about it once or twice in those 6 months. If you do the work for less money, great for them.
Poor work-life balance for some teams, especially for those under manager level.
Management and senior management taking decisions opposed to C-level guidance and once found out, asking the employee to re-do the work and blaming them for "not understanding" what was required even if in internal meetings it was clearly communicated that we are going against the recommendations.
Management ready to complain about what you deliver, even if you stick to the brief from the stakeholder. Very poor understanding of stakeholder management.
Hiding under the rug mentality all over the company.
