Fabio,

It's documented UNION behavior not a bug. From the help, "When two columns of different data types are involved in a UNION operation, the data type with the lower precedence is converted to the data type with the higher precedence".
In regard to not submiting bugs to MS, it's just childish behavior on your part.
