Those 2 class attributes are never used. Good thing, since you really
want each employee to have his own name.

Those 2 function calls will happen only once, long before you
instantiate any instance of employee. Put those inside the method, not
as default values.

The __init__() method should look something like this. That way,
collect_name() and/or collect_id() will be called if the corresponding
argument is not given.
def __init__(self,name = None, id=None):
if name:
self.emp_name=name
else:
name=collect_name()
if id:
self.emp_id=id
else:
self.id=collect_id()

Please switch to text mail, as the html will mess things up, sooner or
later.
