Company wants copy of unpublished work. Should I give it? A prospective employer requested a copy of my PhD thesis and some unpublished papers (still working on them). Is it wise to hand these to them?
From the ethics course we had to take during the first semester of grad school: it depends. 

If your research contains anything that is waiting to be patented, then you can't pass it on to a potential employer. 

If your research was funded by industry, then you can't pass on unpublished work without the permission of whoever funded it (you could get sued). 

If it is part of a larger project that your advisor is working on, then you shouldn't pass it on without their permission (you probably won't face legal action, but your advisor could be very upset with you). 

As Nate pointed out in the comments, if you have coauthors for any of this material, you need to check with them before passing on anything.

If it was funded by anyone who made you sign confidentiality agreements, then you can't pass it on without permission (I know people who receive funding from the NSA for cryptography work, or the DoD to work on certain engineering projects who had to sign such papers).

If your chapters contain medical or otherwise personal data collected, make sure it has been anonymised to whatever standards there are in your field (HIPAA etc).

If none of these apply, then you can probably pass it on without problems. I would still check with my advisor if I were you though, just to make sure.
