Apple Employees Keep Walking Into the Glass Inside of New Offices Apple's new headquarters is causing some problems that pertain to the glass making up the $5 billion "Park." Bloomberg reports that numerous employees are walking into glass walls around the park, leading to some workers placing post-it notes on the walls to make their presence more obvious. However, the post-it notes were ultimately taken down. The building is designed to house some 13,000 employees, featuring office spaces that are glass pods. Apple opened its new corporate headquarters to employees in April 2017, while a visitor center opened to the public in November.
