Thats a really great idea-- following up on our services rendered. Wow. Wish I had thought of that.
At one of the privates I work for, we have a wall made of (cork) message board, with cards and letters from patients. Some of them are Christmas cards from regular dialysis patients, some neatly handwritten thank you notes. Employee names mentioned are highlighted and thus publicly congratulated. If a facility of patient calls a supervisor to compliment an employee, it is typed up and posted, and the employee usually gets a letter in their file and sometimes a box of chocolates or the like (from the company).
We have a corner of the board dedicated to obituaries-- of frequent patients and friends of the company. We try to make sure that we have a respectful presence at all memorial services. We were indeed a part of their lives-- and sometimes their dying days. If we can be as supportive to the grieving family and friends as were while the patient was alive, we try to. Not only were we a part of the patient's life, but they were a part of ours. Some patients have had the same crew pick them up every tuesday morning for several years-- and employees mourn alongside family and friends.
I'll make one addition: The company I talk about prides itself on being a member of the community (actually, both of the privats I work for do this... humm...). The owners live nearby the station, supervisors not much further, and much of the staff dotted around our response and coverage areas. Our patients are quite literally, sometimes, neighbors. And that is the difference between us and our competitors. Humm...
