We have no objection with that as a security measure. Our union's only fear is that those video cameras will be used for other things. They must not be used to penalize our members by seeing if they are doing their jobs, or to examine workers like you examine a microbe under a microscope. That is what we do not want.
The case law is clear on the issue. When there are strategic points for which the use of cameras is justified and when there are no other ways of ensuring safety, we have no difficulty. However, the cameras must not be used to spy on workers to see whether they are making mistakes or not. That is the position that we have always taken.
