Re: May 10, 2012: "Unplugged"
Acceptable jobs that one is required to be on call 24/7.
Even with the following listed, one is only on call for a certain period of time...ie a week out of the month, then one usually swaps out with another:
Corporate Attorney (Attorney might be truly 24/7 if on retainer)
Project Engineer for any industrial complex (usually will go in rotation with other project engineers)
some kind of Civil Utility Manager
