We've had some suspicious coincidences at my work in the past couple weeks.
We were talking on shift about how we didn't have a tip jar so made one ourselves, the next day (without communicating with anyone or coming into the shop) our boss had a proper tip box ready to install.
In another case 2 staff were talking about a personal Instagram account that could only be found by typing the exact handle, and that night it was followed by our boss (who has said many times that he fancies her).
There are cameras that we are aware of however they're not able to see a phone screen (for the Instagram page). They have been caught recording and listening to us through cameras before a few years ago however this is a new location.
Is this legal? We're in the UK and at the very least feel very uncomfortable knowing that they could be listening to everything we say.
