Revenue From Contract With Customer [Abstract]

Disaggregation of Revenue

In the following table, revenue is disaggregated by service types and timing of revenue recognition and includes a reconciliation of the disaggregated revenues by reportable segment.

As described further in Note 14, effective in the first quarter of 2020 our segment reporting was realigned due to our Right Management business being combined with each of our respective country business units. Accordingly, our former reportable segment, Right Management, is now reported within each of our respective reportable segments. All previously reported results have been restated to conform to the current year presentation.
