"Contrary to claims appearing on the internet, Professor Grimm’s work was not under formal review nor had he been given any notice of dismissal. It is standard practice at Imperial to conduct both informal and formal performance management. Professor Grimm’s line manager met with him on a number of occasions to see how the College could help him to develop more competitive grant applications, for example through internal peer-review, collaborations and letters of support. Discussions included talking about the best place for him to do his science, both inside Imperial and outside, and, with Professor Grimm’s permission, his line manager made enquiries about opportunities on his behalf."
So this may still be a situation of pressure being brought to bear, just in some manner other than via formal review.
