LAS CRUCES — Sitel plans to close its Las Cruces call center, putting roughly 400 employees out of work. According to Shirley Loebsack, with Sitel's marketing and communications department, the decision to shutter the operation was the result of the company's business model and does not reflect on the performance of the Las Cruces center. The anticipated closing date is March 26. "Sitel has had the honor of working in the Las Cruces area for 10 successful years and our associates have been extremely active and contributing members of the community. Unfortunately, our business model does not allow for us to remain in this market. Please know this was a business decision and is not a reflection on associate performance or the quality of the team. Based on this change, Sitel issued an official WARN letter to each associate and to the state of New Mexico as required by law on Jan. 5, 2017," according to the email.
