"Clopening"

"Nope. No, I was actually scheduled to be on today. Nevermind."

Clopening - n./v. - 1. The event or action of working an opening shift immediately following a closing shift.

Ex:
Are you on tomorrow?
Are you kidding? I'm clopening.


Frankly, I just loath any shift longer than the number of hours I had to sleep between shifts, let alone the number of hours total between shifts.
