In particular, I'm interested to know what to do in terms on handing over things like passwords to systems. Should I demand passwords to be changed immediately so that I don't have access?
The situation is that people taking over my work aren't well qualified, it could be easy to blame an ex-contractor for any problems, while trying to save their own job. I'm trying to protect myself from potential blame being assigned to me, if things go wrong with systems/networking/websites etc.
I have documented as much as I thought was necessary/requested. I have also got in writing confirmation that my contract is ending on certain date.
Just to add also, the fact that, like contractors, I am waiting for my invoice to be paid for quite a while after completing work. So getting blamed at this stage, while waiting, could result in at worst needing to clean the mess for free, at best being paid to clean the mess.
