The last week of work prior to mandatory shutdowns has a ghost town feel to it with many people already on leave.

One of the remaining few has expressed the theory that if the last day of the week is casual dress then the last week of the year should also be casual dress.

Sounds fair enough for me. 

Of course it'll only apply to me for one day since tomorrow is my last day at work for the year.

But that also works for me. :D
