I need to combine both select statements into one select

SELECT count(tbl_employer_post_details.employer_id) pending
  FROM tbl_employer_post_details, 
       tbl_employer_registration
 WHERE job_status=0 
   AND tbl_employer_registration.employer_id = 
                                   tbl_employer_post_details.employer_id
 LIMIT start,max;

And the second query, with the only difference being the WHERE job_status=1:

SELECT count(tbl_employer_post_details.employer_id) approved
  FROM tbl_employer_post_details, 
       tbl_employer_registration
 WHERE job_status=1 
   AND tbl_employer_registration.employer_id = 
                         tbl_employer_post_details.employer_id
  LIMIT start,max;
