Exhibit 10.1

CDI CORP.

Amendment To Employment Agreement

This is an amendment (Amendment) to the Employment Agreement entered into as of the 1st day of January, 2008 between CDI Corp., a
Pennsylvania corporation (the Company), and Roger H. Ballou (Executive). This Amendment is effective as of March 19, 2009.

Background

in 2009. Specifically, the parties desire to reduce the level of pre-tax profit (PTP) that the Company must achieve in order for Mr. Ballou to earn PCDS and to reduce the dollar value of PCDS earned by Mr. Ballou.

Agreement

Accordingly, for
good and valuable consideration, the receipt and sufficiency of which is acknowledged by each party, and intending to be legally bound, the parties agree as follows:
