Bash multiple combined conditionals

if [[ $failedjobs = "<empty>" || $failedjobs = "" ]]  &&  [[ $completedjobs = "<empty>" || $completedjobs = ""]] && [[ $runningjobs = "<empty>" || $runningjobs = "" ]]

I would like to check if failedjobs is "empty" OR "" AND completedjobs is "empty" OR "" AND runningjobs is "empty" OR "".
