Sometimes it is obvious – the change will impact on them negatively, they don’t agree it is the right direction for the organisation, it is being handled really badly – you know these and many other reasons.  This article from @HBR suggests another interesting idea – that there are competing commitments holding them back from the change.  This means that they may be holding a deep seated idea of their place in the world and that this change will threaten or undermine that.  Worth a thought next time someone is unexpectedly not responding as usual.  Good coaching can help people see some of these underlying ideas and begin to unravel them – giving more opportunities to respond more skilfully to the next tough challenge life offers!
