I am very much noting two crucial things in this case.
The time line
and
The level of influence and power Upton had.
I am fairly sure that establishing a time line events will be the bread and butter of any employment tribunal regarding allegations of harassment and bullying and thats one of the first things a judge will take a look at.
NC has made a point of highlighting power and control issues surrounding Upton. The judge can't ignore that because of the way its been done.
The lack of questioning of this level of power is now really being highlighted in ED's testimony.
In this sense, Upton has not been able to control the narrative to date despite attempts and actually when the defence have cross examined their own witnesses are only serving to highlight these two central issues.
