Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies In the ordinary course of business the Company is the subject of, or party to, various pending or threatened legal actions which could result in a material adverse outcome for which the related damages may not be estimable. As previously disclosed, the Company entered into a settlement with plaintiffs in Hillson et. al. v Kelly Services in order to avoid the cost of continued litigation. On August 17, 2017, the District Court approved the settlement and entered a Final Order of Judgment and Dismissal. The Company made the final payment, which was accrued in 2015, on September 19, 2017. In addition, the Company is continuously engaged in litigation or investigations arising in the ordinary course of its business, such as matters alleging employment discrimination, wage and hour violations, or violations of privacy rights or anti-competition regulations. There are matters that are currently stayed pending a decision from the Supreme Court of the United States on whether the Company’s arbitration provision is enforceable. We record accruals for loss contingencies when we believe it is probable that liability has been incurred and the amount of loss can be reasonably estimated. Such accruals are recorded in accounts payable and accrued liabilities on the consolidated balance sheet. While the ultimate outcome of these matters cannot be predicted with certainty, we believe that the resolution of any such proceedings will not have a material adverse effect on our financial condition, results of operations or cash flows. At year-end 2017 and 2016, the gross accrual for litigation costs amounted to $5.3 million and $9.2 million, respectively, which are included in accounts payable and accrued liabilities in the consolidated balance sheet.
