Perhaps the managers were not signaller competent?
Three points.
1) Network Rail LOMs usually have to 'sign' at least some of the boxes/panels/workstations in their area. In my experience, LOMs responsible for single-manned areas typically 'sign' most, if not all of 'their' boxes (and are often used to provide emergency cover when a box might otherwise have to close).
2) In the video embedded to the first page of this thread, Mr Lee states that he initially believed the two managers had arrived at the box to provide him with his 20-minute break. This implies that at least one of the two managers was qualified to work the box.
3) Although Mr Lee began the process of closing the box, this was not completed and the box remained open even after he was suspended. The presumption, therefore, is that once Mr Lee relinquished his duties, one, or both of the managers worked the box (which would only be possible if they 'signed' it).

What was the signallers shift?
According to
this Daily Heil article, Mr Lee was working an eight-hour late turn (1400-2200).
