If it is sensitve and falls under HIPAA or SOX regulations, then you'll
probably have to have both good security measures and security accounting
practices (i.e. log users commands, etc).

If they are being truly un-cooperative because they do not want to work
within the guidelines that managment (or regulations) have set down, then
it is beyond a technology "fix" and is now a managment/HR
issue.  Even if you do come up with a solution today that stops them
from changing their home directory with a chmod, what's the next back door
they'll find?  If it is a HIPAA/SOX imposed regulation they are
bypassing, it could have severe finiancial reprecussions to both the
company and possibly themselves.

I believe that you can use the "sudo" command to both log and
permit combinations of actions.  In a simplistic world you could
permit a "sudo chmod 775 $X" where $X is not in (/home/*), but
then you start geting people who are creative with the $X variable

Good luck!
