first at all... don't capitalize a class variable! => @emplozeetenure is
correct
2nd: i don't remember that there is a to_d method. use to_f, because
float has always double-precision in ruby
3rd: don't use to_f better use to_i... if there compared number anyway
is a Integer (Fixnum) then better to compare it with a Fixnum.
