The load moves before it grows
The first effect of a second shift is that the quiet window disappears. A site that previously emptied at four now has people on the floor until midnight, and the attendance that used to follow the end of the day now falls in the middle of an operating shift. That is a timing problem before it is a volume problem, and it is the one that produces immediate complaints.
Resolving the timing usually means moving the attendance rather than adding to it. The new quiet point may be between shifts, after the second shift ends, or during the early part of the first shift when the previous night's activity has cleared. Establishing where it now falls is the necessary first step before any conversation about additional hours.
