Interesting fact that we have been short changed

A colleague sent me the following in an email which I replicate in its entirety:

Hi all,

Let me tell you a story about
13-month bonus......
Why there is a 13-month bonus when it is really isn't a
bonus? The mystery is finally revealed! When the British were in Singapore, they were being paid
weekly & they argued that Singaporeans were actually being cheated into
believing that the 13th month pay is a bonus.

Singaporeans are being paid monthly which
is equivalent to 4 weeks pay coz there are 4 weeks in a month. As the British
were paid weekly, it worked out to the same. You see, there are 7 days in a
week. 4 weeks in a month. 12 months in a year. Then 12 months should work out to
48 weeks only.

But 1 year actually has 52 weeks!!! Hence the 13th
month is your own pay not bonus??!!). So, the British argued that there is in
fact no bonus at all??? It is a very simple calculation that stunned
many!!!!

BONUS??? What
bonus??? .
Now you understand ?
