Apple’s health team is reportedly in turmoil, according to a CNBC report.

The team has seen a slew of departures in the past year after a series of leadership changes and internal disagreements about direction.

According to eight people familiar with the situation, some employees have become disillusioned with the group’s culture, where some have thrived while others feel sidelined and unable to move their ideas forward.

Four of the eight people said some employees hoped to tackle bigger challenges in healthcare — such as medical devices, telemedicine and health payment — but the focus has been on features geared to a broad population of healthy users, instead. All eight people confirmed that health remains a strategic priority for Apple, which goes in line with what the company’s CEO Tim Cook has been saying for quite some time now. In fact, Cook said he hopes that health will be the company’s “greatest contribution to mankind.”

What is not clear though is whether the attrition rate within the health team is higher than in other groups within Apple. If you remember, the now legendary iPhone designer Jony Ive left the company earlier this year, and there were also other departures.

Unsurprisingly, Apple declined to comment for this story.
