I am a department director in a health care organization.  When I was initially hired 9 years ago, the leadership on the unit had reduced all self esteem and trust to the point that several staff were recording conversations with leadership so they had "evidence" or taking notes so they could prove what was actually said or done.  Needless to say it was a difficult situation to walk into.  But, with patience and by focusing on the positives rather than all the changes that need to take place, we were able to develop trust and create a very different culture.  September I will have been here 10 years.  I'm happy to say, it only took about a year to lay down the foundation that has led to a department with very low turnover and very positive patient and partner satisfaction.  Kindness and a positive approach are key to creating a positive culture.  Regardless of an organization's culture or what's going on in other departments, you can change the culture in your work area.
