DBA to work from home
It depends...

Anyone can work from home if they have the proper work ethic.  If your very self motivated and task oriented then it will work fine.  It is important that you are able to show the people that you report to that you are producing top quality work.

As a manager it is harder for me to manage remote employees because I have to work harder to make a personal connection with them and ensure that we are working well together.  I have some great people that work for me, database professionals, that work from home hundreds of miles away.
