A couple of weeks ago two of my colleagues went around the office filming for another colleague's anniversary video. The filming took place on company premises during work hours, and I understand it was their own initiative.
I have a strong aversion to being filmed. After they were through I contacted both via Skype telling them I do not consent being filmed, and asked for a courtesy warning next time, so I can get out of their way. I have a cordial relationship with both. The little footage of me they got made it to the final cut.
Another anniversary is coming up, and one of them decided to recruit a third camera-man, and the two of them came into my office again, smartphones in-hand. Again I left the office to let them do their thing, but I'm not too chuffed about this. No courtesy warning was given and I suspect the original pair didn't take me too seriously the first time.
Our company handbook doesn't mention video recording anywhere (except when outlining CCTV policy), and the only relevant bit I found was that mobile phone use is to be kept to a minimum during work hours.
I'm contemplating starting a Skype conversation with both colleagues, as well as the second-time offender's manager, who I'm also cordial with, to ensure that none of this footage makes the new video. I plan to keep it friendly and informal in tone.
Ideally I'd like them to warn me next time they feel like shooting videos while not kicking up too much of a stink about it - just the right amount. I have a few days until they edit the video.
How can I effectively address the issue of being recorded against my wishes?
Resolution: I accepted DarkCygnus' answer as it avoids escalating while having a good chance of being effective, and spoke to both of them again. The reaction I got from the 'new recruit' was quite telling:
Some people say they don't wanna be in the video, I guess you really don't wanna be in the video.
This makes it clear to me that he didn't realize I was being serious. Without me saying anything other than I don't like being filmed after sitting down with him, he immediately assured me I won't be included in the final product.
As for the other guy, the 'second-time offender', I was unable to meet in person but I reiterated my concerns over Skype. I explicitly told him I don't consent being filmed and that I don't want to be in the final video. I repeated my offer to get out of his way with a little heads up. He acknowledged all.
If, despite all this, they decide to include footage of me, I plan to speak with HR to have the company handbook updated for those of us who don't like being filmed. I don't plan to point any fingers, merely highlight those concerns of us more inclined to privacy.
Edit 2: Unfortunately, I was completely ignored. The video was shown in the staff room over pizza, with my face prominently in it. First thing today I wrote to HR to clarify our policy on the matter. The two HR ladies both assured me they are in total agreement with me, and to leave the matter in their hands - and I'm happy to do just that.
Changing the accepted answer to AndreiROM's. Managers are there to resolve conflicts before HR needs get involved, we might as well use them.
