Apple opened its glittery, circular, spaceship campus in Cupertino a few months ago. This campus is the of dream of Steve Jobs, which he pitched to the Cupertino City Council in 2011. It reportedly is estimated by the Santa Clara County Assessor to have cost $5 billion.

The gigantic, circular building comes with 45-foot-high curved panels of glass, among other modern, glass features.

And while the building is ultra-high-tech, there have been reports that a few employees unwittingly walked into glass doors and walls, while reportedly sustaining cuts.

To prevent further incidents, some Post-it notes were placed on glass panes to warn other employees not to walk into them. Apparently, those Post-it notes later were removed, as they do not fit into the look and feel of the premises desired by Apple.

While MarketWatch reported from obtained records that the cuts of a couple employees were sufficiently severe to “warrant calls for local emergency services in the early days” after the opening of the new campus, none were so serious as to require hospitalization. Furthermore, so far there have not been any reports to the US Occupational Safety and Health Administration.

While it is regrettable that there have been a few glass-related incidents, it is important to keep in mind that the vast majority of the many Apple employees now situated at the new campus have not been injured by walking into glass.
