Be loyal to your employees and they'll be loyal to you.
One of the difficulties with this is the corruption of the management at Oracle. If the management were made up of competent people, then they could do this, and all would be well.
But, the management at Oracle is made up of some really incompetent people. Those people cannot work in a normal way. If they hire good people, then those people will very quickly find out that the managers they are working with have no idea what they are doing. They can band together to overthrow that manager and then the manager is the one out of a job.
The way to stay in power and keep your job, if you are an incompetent manager, is to hire and promote other incompetent people. Then, they all can work together to make sure that no one better than them overthrows them.
This is what the real problem is. To keep the better people from moving up and replacing the incompetent managers, you have to keep them in their place. Management then works to separate competent people from each other. They incite and intensify differences between good people to keep them from working together.
If you have not read the lawsuit documents for the TG and SPMK lawsuit that was posted on here, you need to read that. That lawsuit shows you the pattern for how an incompetent manager tries to maintain control. TG is the manager in question. He lied about three reports working under him, telling each of them that the other two were worthless and he couldn't get any work out of them. This incites each one to avoid the others and try to do all the work themselves. TG was upset when one of them deliberately ignored him and brought all three of them together to work together. TG's response to them working together was one that looks paranoid to most of us, but from TG's perspective, incompetence, having his reports work together was a massive threat and he was sure they were working to get rid of him.
The result is the firing, lawsuit and eventual su----e of SPMK, the person who was trying to do the right thing for the company and technical success. The stress from working for management that is continually lying to you and about you is intense. I know, I have gone through it.
They lie because they are incompetent. They harass and intimidate the people below them because they are incompetent. Therefore, unless the management is replaced, the harassment and intimidation will continue. It is the result of the incompetence and fear that managers like this feel when they are trying to stay in power.
It cannot be fixed any other way. The management is in control of these conditions. They harass and intimidate to stay there. It is what it is, as they say.
It will not change. Get out of the company!
