I agree with you.
1. Leadership. Leaders need to be visible and in touch with their front line staff.
2. Engaging line managers. Studies show that most of the variation in engagement levels is down to the line manager.
3. Employee voice. An empowered employee will have a voice. Where employee views are sought out they should be listened to and visibly acted upon.
4. Integrity. Behaviour throughout the organisation is consistent with the stated values, leading to employee trust and a sense of integrity. The larger the gap between the two, the more distrust exists.
