Perhaps you weren't including the use of autonomous transactions?
CREATE OR REPLACE FUNCTION remove_emp (employee_id NUMBER) RETURN NUMBER AS
PRAGMA AUTONOMOUS_TRANSACTION;
tot_emps NUMBER;
BEGIN
SELECT COUNT(*) INTO TOT_EMPS FROM EMP3;
DELETE FROM emp3
WHERE empno = employee_id;
COMMIT;
tot_emps := tot_emps - 1;
RETURN TOT_EMPS;
END;
SQL> SELECT REMOVE_EMP(7499) FROM DUAL;
REMOVE_EMP(7499)
              12
SQL> SELECT REMOVE_EMP(7521) FROM DUAL;
REMOVE_EMP(7521)
              11
SQL> SELECT REMOVE_EMP(7566) FROM DUAL;
REMOVE_EMP(7566)
              10
