U.S. Secretary of State, Rex Tillerson, has said life as a CEO was “easier” than working in government for the Trump administration.

Mr. Tillerson spoke candidly to reporters on the plane returning from his latest diplomatic tour, which included visits to Ukraine, Turkey, Germany, Qatar, and France, the Los Angeles Times reported.

“Well it is a lot different than being CEO of Exxon because I was the ultimate decision-maker…that makes life easier,” said Mr. Tillerson.

He had spent four decades with the oil company and had grown accustomed to his staff and the organisation he helped shape.

Mr. Tillerson said that as an executive he was used to making unilateral decisions.

“You own it, you make the decision, and I had a very different organisation around me. One that I spent my whole life with, people knew me very well and they knew what to expect,” he explained, adding that he was exhausted from the recent tightly-scheduled tour.

He described the Exxon Mobil decision-making process as “highly structured” which he felt allowed the company to “accomplish a lot in a very efficient way.”

That is simply not the case in the bureaucracy of the State Department or with his somewhat contentious relationship with White House, who have reportedly complained about the several vacant deputy positions in the agency.

However, it has been reported that the White House has cut Mr. Tillerson out of being overruled by Donald Trump on certain appointments, the LA Times reported.

It may not be of help that the White House wants to cut the agency’s funding by nearly 30 per cent in the next fiscal budget.
