There is a lot of interaction between lower level staff and the upper (SES) management. There is genuine discussion and listening to feedback.
Have several managers that I can speak to on a regularly basis, all have great people management skills.
I have had access to both of my managers and both of my team leaders at all times when I need them, as well as senior staff with experience and advice to share. I have regular correspondence with the SES in my organisation, and they are accessible in office hours without difficulty. I do not require any greater access to senior staff than I have right now.
Depends on the individual. Certain managers are very approachable and available, others not so much.
My current manager is an excellent mentor. I have also found the executive very approachable and supportive.
The two managers I have had most contact with have been very supportive. My team leader communicates well and provides meaningful and useful feedback. In addition I have done some other work with very senior members of the executive and found them very supportive too.
