When a small or midsized business is short on labor, SOS Staffing Services answers the call for help. Founded in 1973, the company provides personnel in 15 western and midwestern states for industrial, clerical, and professional positions. SOS also offers payroll, drug testing, risk management, and outsourcing. Operating segments and divisions include Adams & Associates, PAMS (short for Patient Accounting Management Services), and TOPS Staffing. Its Employment Trends affiliate provides staffing services in the entire Pacific Northwest while its Devon & Devon unit zeroes in on the California market. SOS was acquired by Hire Calling Holding Company in 2003.
In 2009 SOS Staffing merged its Hire Calling and Employment Trends units, keeping the Employment Trends name. The newly combined firm offers temporary-to-hire and temporary personnel across a wide variety of areas throughout the Oregon region.
