Those stuck within the workflow support team, and those placed under teams with certain managers. I will not name them directly, but know that working here you will be at the fate of whatever mood your manager percieves you in. The downside to them is that some of them in certain departments are honestly quite lazy, and very disconnected from the teams they work with. They aren't aware of all the things ongoing within the company, and in truth it becomes more of a brownnosing enviorment to stay around. For example there was one employee who spent close to three years not doing his job in the company and underperforming and in some cases creating more work for other members of the team. Yet, at the end of the day he was allowed to stay on until enough complaints were brought up to HR simply because he was friends with the manager. This goes into line with other individuals throughout the company as well, many of them are just friends with the managers and thus secure there roles and positions.
There is also another issue, in that many members of the staff are very incline to keep certain information or skills to themselves and are not willing to share the information. The feeling that you need to validate your own importance exists here with the company, otherwise you'll be passed over for promotion or have a less likely chance to be terminated due to the importance you place yourself as.
