Allow User To Disable Event Code

I have these codes in place in my excel file, there is nothing wrong with them at all. Here is the the problem : My superior runs the macros in place in the file almost daily, and when he is done he then closes it and all is well.
The macros does things to other files so they are changed in a way that the supervisors like them. I avoided putting macros in these individual files, because of the attempt to make it as simplistic as possible without them being able to affect overall file.
The problem happens when he (my superior) accidently makes a change in the primary sheet in the workbook with all the macros, it affects alot of my formulas and macros that are already in place. Within this workbook, it keeps a log of things from the other files results, so I have to have a record of it in the workbook, hence having a save event in place.

The Question: Is it possible to create a macro button, that will allow him to disable the codes below, so that he can close it and open again, so that it doesn't show any of the errors that happens by accident and try to close it again so there is no errors? Basically, I am asking what is the code for this, and where would I place it in.


Private Sub Workbook_BeforeClose(Cancel As Boolean)
Dim mylogoff
Set mylogoff = Sheet1. Range("A65536").End(xlUp).Offset(0, 1)
mylogoff.FormulaR1C1 = "=NOW()"
mylogoff.Copy
mylogoff.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
Application.CutCopyMode = Fals
mylogoff.Offset(0, 1).FormulaR1C1 = "=RC[-1]-RC[-2]"
Application.DisplayAlerts = False
Sheets("Start Here").Select
ThisWorkbook.Save
ThisWorkbook.Close
End Sub......................
