Need help figuring out a query

I am struggling with what should be a fairly easy query but cannot seem to figure it out so any help is appreciated.

to keep it simple I will not include everything in my query here, but just where the problem seems to lie.

I am selecting so basic fields from the JOB record, and then some fields from the LEAVE_ACCRUAL.

JOB.EMPLID, LEAVE_ACCRUAL.PLAN_TYPE, LEAVE_ACCRUAL.HRS_TAKEN_YTD where LEAVE_ACCRUAL plan type is in('50','51')

so for instance I could get

EMPLID     PLAN_TYPE     HRS_TAKEN_YTD

000001     50                              8

000001     51                              16

000002     50                              10

000003     51                              8

So not all employees have both sick and vacation ( plan types 50 and 51)
