Sure.

Assuming you keep each class in a seperate file:

require 'person'
#require 'employee'   # this is not necessary

class Accountant < Person
   def initialize()
      @payrollid = Employee.getnewid()
   end
end


Of course, for the code to work, then somewhere in your application,
*some* file must require employee.   If you want to make sure that
each file will require everything that it will need at runtime -- for
example, if you are going to do unit testing -- then one solution is
to do this:

require 'person'

class Accountant < Person
   require 'employee'

   def initialize()
      @payrollid = Employee.getnewid()
   end
end
