Lets take a look at what you are asking for :
There are 365 days in the year available for work.
There are 52 weeks in the year, in which you already have two days off per week, leaving 261 days available for work.
Since you spend 16 hours each day away from work, you have used up 170 days, leaving only 91 days available.
You spend 50 minutes each day in coffee breaks which accounts for 25 days per year, leaving only 68 days available.
With 1 hour lunch period each day, you have used up another 46 days, leaving only 22 days available for work.
You normally spend two days per year on sick leave.
This leaves only 20 days available for work.
We are off for 5 holidays per year, so your available working time is down to 15 days.
We generously give you 14 days vacation per year, which leaves only 1 day available for work, and I’ll be damned if I’m going to let you take that day off.
