Personally, I’m fine with a working lunch, as long as I stay clocked in. Because it means I either pick up OT at the end of the day, or I get to leave early. But this only works because I have a fairly flexible schedule, set my own meetings, etc… And I certainly wouldn’t try to enforce it on my coworkers, because they may want to be able to walk away and disconnect for a while.
Meal time is time for whatever you want to do; If you want to stay at your desk and play catch-up on some emails, then great. If you want to walk away and de-stress for an hour, then great. Neither one should be the expectation, because the time should be at the employee’s discretion, not the employer’s.
If this is the same Ghostery that makes the Chrome/Firefox extension, they were in hot water a few years ago for selling the extension to an ad agency. That ad agency almost immediately turned around and started selling usage data to the sites whose trackers were being blocked.
Basically, Ghostery was selling info about how users were using the extension, how their trackers were being blocked, and which trackers were present on different users’ browsers. And the extension had this data collection quietly turned on by default. It also meant that ghostery was only acting as a middleman in the data collection process (and profiting as a result,) because the trackers were still able to get the info; They just had to pay Ghostery for access.
