Please see my comment in a good write-up on trust in the following link,and author's response.
I find organisations lack team-spirit because trust is absent.But,what needs to be done?I recommend following;
1] Every person in an organisation should learn to respect other.
2] Team is built when people identify with a common goal.Organisations must help people identify that common goal.
3] Team leaders must generate trust by setting an example.They have to become role models.
4] Values-based training based on organisation's thrust areas should be given emphasis.Values must blend well with organisations'thrust areas
5] Trust is built when people are emotionally attached with each other,which helps in building team-spirit.Organisations have a big challenge here.
