Yet another linker error (class declarations included)

[GraemeW]

Im getting this error in my code

[Linker Error] Unresolved external 'Employee::Employee(_STL::basic_string<char, _STL::char_traits<char>, _STL::allocator<char> >, _STL::basic_string<char, _STL::char_traits<char>, _STL::allocator<char> >, bool, int)' referenced from C:\SECURITY\MAIN.OBJ

See Updated Code Below

I think the error is on the last line in my main code, "Vector.pushback( new Employee( S, F, Auth, ID ));"
I can't see a single error in those class declarations? Can anyone tell me whats wrong?
