Creativity is critical for workers looking to protect themselves from being replaced by new technologies and automation, a tech expert told CNBC.

Speaking to CNBC's "Squawk Box Europe" on Tuesday, John Abel, vice president of cloud and innovation at Oracle, said the notion of regularly reskilling employees to adapt to new systems was becoming less effective.

Oracle is a U.S. firm specializing in emerging business technologies and software.

"Reskilling is a here and now (solution), then we're done," Abel said.

"You need to bring out — in all of your workforce — creative skills, because as we know with the modernization of IT, and specifically with A.I. (artificial intelligence) machine learning, anything that's a logical processing job will be at some point replaced, so what we're asking our staff to do is use their creative skills across all age groups (in) the workplace because that's the unique advantage."
