“I want to hold them captive all day long,” Ellison, chief executive officer of Mineral Resources Ltd. said on Thursday. “I don’t want them leaving the building. So I don’t want them walking down the road for a cup of coffee. We kind of figured out a few years ago how much that costs.”

Ellison was championing the perks of working at the firm’s two-year-old Perth headquarters, which boasts a cafe, restaurant, gym, creche, reflection room and wellness center. The 67-year-old mining veteran said that staff “loved working” in the building and its facilities “kept them glued” there.

“I have a no-work-from-home policy,” he said in the transcript of a call with analysts following an earnings update. “I wish everyone else would get on board with that, the sooner the better.”

“We can’t have people working three days a week and picking up five days a week pay.”

Ellison’s office policy is something of an outlier in Australia, where working from home has become the norm for white-collar workers. Many companies allow their employees to work remotely at least two days a week, with many parents embracing their new-found flexibility.

And for those juggling busy work schedules and children, Ellison said the company’s daycare center would charge just A$20 ($13.58) a day, compared to external costs of around A$180 a day. 

“Drop the little tykes off next door,” he said. “We’re going to feed them, but mum and dad will be working in our office.”
