Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation Various suits and claims arising in the ordinary course of business are pending against us. We conduct business throughout the continental United States and may be subject to jury verdicts or arbitrations that result in outcomes in favor of the plaintiffs. We are also exposed to various claims abroad. We continually assess our contingent liabilities, including potential litigation liabilities, as well as the adequacy of our accruals and our need for the disclosure of these items, if any.

We have $0.4 million of other liabilities related to litigation that is deemed probable and reasonably estimated as of June 30, 2014. We do not believe that the disposition of any of these matters will result in an additional loss materially in excess of amounts that have been recorded. Between the second quarter of 2013 and the second quarter of 2014, five lawsuits with similar allegations of violations of California's wage and hour laws were filed in California. The lawsuits allege failure to pay wages, including overtime and minimum wages, failure to pay final wages in a timely manner, failure to reimburse reasonable and necessary business expenses, failure to provide wage statements consistent with California law, and violations of the California meal and break period laws, among other claims. We intend to vigorously investigate and defend these actions; however, because these cases are in the early stages, we cannot predict the outcome of these lawsuits at this time and, accordingly, cannot estimate any possible loss or range of loss. In April 2014, we became aware of an allegation involving our Mexico operations that, if true, could potentially constitute a violation of certain of our policies, including our Code of Business Conduct, the U.S. Foreign Corrupt Practices Act (“FCPA”) and other applicable laws. We conducted an initial investigation of this matter and our Board of Directors formed a special committee of independent directors to oversee the investigation of this matter as well as the investigation of previously disclosed possible violations of the FCPA involving business activities of our operations in Russia, and any other resulting matters. The special committee has retained external independent legal counsel to conduct these investigations going forward. The special committee’s investigations, which also includes a review of certain aspects of the Company’s operations in Colombia, as well as our other international locations, are ongoing. On May 30, 2014, we voluntarily disclosed the allegation involving our Mexico operations and information from the Company's initial investigation to the SEC and Department of Justice (“DOJ”). We are fully cooperating with the SEC and DOJ. At this time we are unable to predict the ultimate resolution of these matters with these agencies and, accordingly, cannot estimate any possible loss or range of loss. Self-Insurance Reserves We maintain reserves for workers’ compensation and vehicle liability on our balance sheet based on our judgment and estimates using an actuarial method based on claims incurred. We estimate general liability claims on a case-by-case basis. We maintain insurance policies for workers’ compensation, vehicle liability and general liability claims. These insurance policies carry self-insured retention limits or deductibles on a per occurrence basis. The retention limits or deductibles are accounted for in our accrual process for all workers’ compensation, vehicular liability and general liability claims. As of June 30, 2014 and December 31, 2013, we have recorded $64.4 million and $62.1 million, respectively, of self-insurance reserves related to workers’ compensation, vehicular liabilities and general liability claims. Partially offsetting these liabilities, we had $19.3 million and $18.5 million of insurance receivables as of June 30, 2014 and December 31, 2013, respectively. We believe that the liabilities we have recorded are appropriate based on the known facts and circumstances and do not expect further losses materially in excess of the amounts already accrued for existing claims. Environmental Remediation Liabilities For environmental reserve matters, including remediation efforts for current locations and those relating to previously disposed properties, we record liabilities when our remediation efforts are probable and the costs to conduct such remediation efforts can be reasonably estimated. As of June 30, 2014 and December 31, 2013, we have recorded $6.1 million and $6.2 million, respectively, for our environmental remediation liabilities. We believe that the liabilities we have recorded are appropriate based on the known facts and circumstances and do not expect further losses materially in excess of the amounts already accrued.
