Well, well! It would seem Scrags has tripped up. A company computer may not have been used, but you do have access to the crew email addresses on the days you are in the office. (Yes we know who you are and the word is out there!)
Also it isn't defamation if it is true.
As for signing off on the current agreement, it is OFF THE TABLE so there isn't anything to sign. TOO LATE.
It is now just a wait and see what the company pull out of the hat next.
