I work for a very large transportation company. We recently got a memo from upper management concerning photography. In a nutshell...
Employees are no longer allowed to post to social media photos or videos of company property - including vehicles, buildings, or other employees.
Even if the photography is done when the employee is off the clock, or the images put the company in a positive light, it is still not allowed.
Employees are not allowed to post to the internet videos or photos of buses or trains that are being used throughout the city.
If an employee is caught using a smartphone to photograph or video company property or vehicles, their smartphone will be confiscated.
Their reason? The image captured is "data" that belongs to the company.
Any employee in violation of these rules may be terminated.
Sounds pretty draconian to me.
