Pay is poor for hours put in. Not disastrous but towards the bottom end of what you expect from a serious print publication.
Diminishing focus on quality as company turned focus from its own publications to supplying content for other sites.
Serious lack of focus on career development.
A culture of 'give an inch, take a mile' from management. The more work you produced (under increasing stress to do so) the more the result was: 'they can handle that much work - let's give load them up with more'. If payment and/or bonuses reflected effort put in; fine. But this was not the case.
