Not turning in for work is just to similar to striking. Don't worry though, their air traffic controllers will be on strike soon. It's that time of year.
They are not doing it to the borders of other countries, why would they complain. I'm sure nationals of other countries stuck at Dover are complaining too. UK MSM don't generally publish complaints about the EU. Why not have a read of European Truckers Weekly where I'm sure there will be plenty of other nationals complaining about being caught up in French bullheadedness. (Again, like last Christmas.)
