Loss Contingencies [Line Items]
Loss Contingency, Actions Taken by Plaintiff		In 2009, the municipality of Sao Paulo, Brazil assessed the Company’s Brazilian subsidiary a services tax on certain equipment rental income earned in 2004 and 2005. In March 2011, the Company’s Brazilian subsidiary filed a tax annulment action in the Sao Paulo municipal court to challenge the assessment of services taxes on rental income. Further, in order to halt the possibility of any further interest being charged against the alleged due tax assessments,			On October 12, 2012, an amended class action complaint was filed in the Superior Court of the State of California, County of Santa Clara, against TeleTech Services Corp. and Google Inc. (“Google”), as co-defendants. The action alleges that the defendants violated California Penal Code Section 632 by recording telephone calls made on behalf of Google to residents in California without disclosing that the calls might be recorded. The plaintiff seeks class certification, cash statutory damages and attorney fees. Pursuant to the Company’s agreement with Google, Google has made a claim for full indemnification from the Company for all expenses incurred by Google in connection with the lawsuit
Loss Contingency, Management's Assessment and Process		Based on an opinion received from legal counsel in Brazil, the Company believes that (i) the ruling issued by the Sao Paulo municipal court was incorrect and in contravention of a Brazil Supreme Court ruling concerning the invalidity of services taxes on rental income, (ii) the Brazilian subsidiary has valid defenses against the assessed services taxes and (iii) that payment of these services taxes is not probable. Accordingly, the Company has not recorded an expense in the year ended December 31, 2012 for the Sao Paulo services tax assessment.			The ultimate outcome of this litigation, and consequently, an estimate of the possible loss, if any, related to this litigation, cannot reasonably be determined at this time. The Company intends to vigorously defend itself in these proceedings.
