There is an extensive database (centuries of data)

….with strikes in The Netherlands and all kind of interesting details. I have chosen  a subset of 2017 (also for training). I keep it simple (being not experienced at all) and only selected the number of strikes over one year. Not surprisingly the number of strikes (often organised by trade unions) shows a dip in our summer season. Holidays are respected (?).

The IISG in Amsterdam is a fabulous organisation and I may suggest everybody to take a look for data
