Tram deadline today?

Even the BBC are leading on the ongoing tram-saga this morning - here ...

... but is the dispute deadline today (as the BBC seems to think) or has it been extended over the weekend (as yesterday's Herald seemed to think)? Frankly, its just another example of the vacuum being filled by seemingly never-ending speculation.

Whenever the actual deadline is, would like to think that a bit of common-sense might prevail, but can't say I'm overly optimistic :-(

Would actually welcome being wrong in my assessment ...
