Technically, the shutdown would NOT start until midnight, Friday night, the END of the 24 hour day.
This is pay for hours already earned. Technically, they have earned this pay. \
Don’t think this has been thought out.
IF I had to shut down a private company, I definately would HAVE to pay them for hours worked & accrued sick pay & vacation pay up to the shutdown minute.
If you were a private company, you’d be bankrupt. And your last checks would bounce.
