Careers at Kelly Services


Kelly Services Inc (“Kelly Services”) seeks to connect talented individuals to employers that are in need of specific skills or experience, and to provide flexible working opportunities to those looking for employment opportunities.


Kelly Services traces its roots back to 1946 and the foundation of Russell Kelly Office Service by William Russell Kelly. 

The Company is credited as one of the pioneers of the temporary staffing business.  It initially offered a range of services that could be performed for customers at the offices of Russell Kelly Office Service.  Customers, however, later requested that services be provided at their own places of business on a temporary basis. 

In the Company’s early years, temporary workers were typically female, and became known as “Kelly Girls”.  In 1957, the Company changed its name to Kelly Girl Service Inc. 

The term “Kelly Girl” later was used commonly to refer to temporary workers across the staffing industry, regardless of the company providing the workers or the gender of the workers themselves.  Kelly Services expanded its service offerings in the 1960s, and took on its current name in 1966 to reflect this change. 

The Company also expanded internationally during the 1960s, opening its first office in Canada in 1968.  This was followed in 1972 by the launch of the Company’s first office in France.

Today, Kelly Services is among the largest staffing companies in the world.  It employs more than 1,000 workers at its headquarters in Michigan, and more than 6,800 workers worldwide. 

The Company provided temporary employment to around 500,000 people in 2018. 

Kelly Services is listed on the NASDAQ and has a current market capitalisation of approximately USD 957.78 million.
