Answer 1

You can use aggregation:

select tDateWorked, empId, craftCodeId, jobId,
       sum(ot) as ot, sum(st) as st
from t
group by tDateWorked, empId, craftCodeId, jobId;

Answer 2

If there are only numeric amounts in OT, ST, just try this:

SELECT
  tDateWorked, empid, jobid, SUM(OT) AS OT, SUM(ST) AS ST
FROM
  Table
GROUP BY
  tDateWorked, empid, jobid
