There are times when a demonstrator doesn’t want to be recognized. One of them is when the boss might sack you if he recognized you in a photograph.
There is an election coming up, and there are a lot of scare tactics around. Each political party is foretelling atrocities that will be committed by the other party if they get into power.
Apparently these demonstrators believe one of the terrible forecasts, that they will have to work through all the weekends without being paid any extra.
Some demonstrators are wearing masks now to prevent the boss recognizing them in photographs in the media. They do not want to stand up and be counted.
