I’m in the process of having to take strong action against one publishing house and am actively chasing another for payment for articles that I have written for them and, in the former case, for several photos to accompany the article. Both articles have been published against agreed terms, so what is the problem with coughing up what is owed?
One problem is that it is taking me longer to chase them than it did to write the darn things in the first place, but I am going to keep going even if I end up taking them down the small claims route.
It is a shame as it takes away both the pleasure of having something published and any feeling of support for that publication, but such is life. There are a lot of shysters out there.
