There's a cleaners' strike in Amsterdam again, so the trash in the Central Station isn't being emptied, nor are some of the trains being cleaned. On the floor at the front entrance was a leaflet from the cleaners' trade union trying to explain why. Actually that lead to a rather clever website with an animation from the trade union FNV explaining why they are working to rule. Tend to have more sympathy with the cleaners than NS.
Dutch railways has really gone down in my estimation over the years, especially in the international ticketing. And when there's a slight hint of bad weather they switch to an emergency schedule. That's when I avoid taking the train altogether.
