In the corporate world, an "Optional Holiday" is an OPTION to take a Holiday on an already declared Government holiday! Funny to know that an already declared holiday was made optional and even funnier I didn't take the option to Holiday!
In my world, an "Optional Holiday" is all of the following:
Less noise, less work
Cleaner toilets, cleaner roads.
Less waiting time in TT room, more usage of internet.
Music volumes high, working speed low.
Long breaks, more breaks.
More facebook, less outlook.
Less of monitor, more of mobile.
How is it in your world???
