JOLTS due Tuesday at 1500 GMT
After another very good non-farm payrolls report on Friday, Fed officials will go into the December FOMC decision confident about the jobs market.
The big question hanging over them is inflation, especially wage inflation.
The main headline in the JOLTS report is job openings and that's expected to decline slightly to 5500K from 5526K but that's not the most important indicator this month.
Instead, Deutsche Bank, says to focus on the 'quits' rate.
"The quits rate is the most predictive of wage trends, which policymakers are closely monitoring," economists at Deutsche Bank write today.
The current rate is 1.9% but that's still well-below the pre-crisis norm.
