When should you consider your workplace a toxic work enviroment?

When officers and senior NCOs aren't doing the right thing, but expecting subordinates too.

This is a great question. There are many things that go into the decisions that need to be made to fix the toxic environment.
1. What is making it toxic?
2. Are there more than one individual that feels it is toxic?
3. Is your CC a part of the problem? If not go to them and give them a chance to fix it.
Unit climate assessment would be a great place to start. If you are worried about reprisal then stay anonymous. If not then put your name all over it.
Here is my thoughts on what constitutes toxic leadership.
1. Little to no morale
2. Cliques
3. NCOs openly bashing leadership
4. SNCOs openly bashing leadership
5. CGOS openly bashing leadership
6. CC abusing his position of authority
7. NCOs/SNCOs/CGOs promoting a do as I say not as I do atmosphere
I am speaking from experience. The way we fixed the toxic environment was through a UCA. A few of us put our names in the UCA and met with the CC about our comments. Sometimes doing the right thing is hard, but if your environment is toxic then you owe it to not only yourself, but other soldiers to ensure these toxic leaders are exposed and dealt with.

You despise going to work and have anxiety when going in. The person who can change things is one who has the higher rank as the culprits. You need to think about this and who you can trust. You will need moral courage.
