I have reread the OP's posts. I am sure the OP thinks her hubby has hung the moon and the company couldn't possibly function without him, but that is surely unlikely. I know the OP is very frustrated by his hours but I have serious doubts that a $50K a year non degreed employee is really being requested to support a 3000 plus employee firm unassisted with respect to IT. This is an exec level position ($250K+ position) and there is no way that he is being put in such a position. I am sure he reports to a CIO (Chief Information Officer) and more likely through several supervisor positions above him. It may very well be that the hubby is not very good at time managment and is just doing in 80 hours what may take a "normal" degreed IT professional 45-55 hours.
In the past I have had employees who talk about "working all weekend" and then had them document their time to the hour and amazingly when I had them write it down they figured out that they were wasting tons of time and not really focusing. I also suggest that the OP ask his supervisor how much time each task should take and record the difference on his time log. Perhaps it is a supervisor issue.
Also the OP's hubby doesn't have a college degree and I am sure he is very smart, but there are things that college will never teach you, but also realize that a non-degreed IT guy CAN be easily replaced. Sure the new guy will have a learning curve but EVERYONE has a replacement. If hubby doesn't have the degree a very smart whipper snapper can come in and do what the hubby is doing in less time and probably with plenty of improvements.
i have been watching this thread. i know she has said that its not helpful to throw this out there - but is she SURE this is not just a cover for an affair? i would be afraid of an affair.
