My sister works in a library too, if moving to the States was an option for her, you would have an extra employee for sure ;)

I'm a test engineer working 4 days a week (80%) which I have been doing now for 8 years. Working full time like I did over 10 years ago and in a different area just wore me out. I need to have more than just weekend days to do what I like. If the majority of my life would be working I would get very depressed for sure.

I like my job even though test work has been rather low lately but fortunately my other tasks are always ICT related too. It also gives me lot os opportunity to spend time online even during work hours.
