Hi joko / factor30
In my case there was no question of any action if I had not gone back to help.
After 2 years I could say I did not rember the job and I did have to stop to think anyway.
As I left under a redundancy / retirement type agreement there were clauses saying I must not make untrue derogatory remarks about the company and I must be fair in my own dealings in retrement and if necessary act as a witness for the company.
Really I think the company had an unfortunate combination of circumstances so that is why I tried to help.
