Perhaps it might not be too wise to report your travelling/reporting delays or otherwise on PPRuNe lest this provides useful information to the protesters?
If you all say that there has been 'no problem', then perhaps the protesters will redeploy accordingly? And then there might be a problem which perhaps there wouldn't have been if they had been kept in the dark about such things?
Just a thought. Anyway, good luck and I hope you're not inconvenienced by these people this week.
