Good workers don't need to be managed but are self-directed by their own desire to do a job well done and commitment they share with the vision of the company.

There is tremendous value in coming in to the office to see your colleagues face to face but sometimes not all work requires it. Perhaps these workers finished their work early as I have often heard that telecommuters are far more productive. If they didn't loop back with their managers then I would question that relationship or the worker. I wouldn't attribute telecommuting as a killer to productivity though.
