An Apple ad tech employee filed a lawsuit against his employer on Sunday over how the company monitors its employees, reports Semafor.

Apple wants its employees to use Apple devices for work, but work-issued devices are so restricted that many employees use personal devices, or tie their work devices to their personal iCloud. To do so, the suit says, employees must allow Apple to install software that grants Apple access to search anything stored on the device or iCloud. The suit claims Apple’s policies allow it to monitor workers even when off duty. The employee claims Apple used its policies to harm his employment prospects.

The suit captures some of the challenges that many corporate workers face: How much access should an employer have to personal devices that are used for work, or how much control should they have over personal codes of conduct? Should Apple lose, it could curb the growing trend of bossware in the workplace.
