From BBC article:
(extract)
"The Christian Legal Centre said the school where she worked carried out an investigation and concluded Ms Higgs should be dismissed for "illegal discrimination", "serious inappropriate use of social media" and "online comments that could bring the school into disrepute and damage the reputation of the school".
The centre said it was helping with Ms Higgs' legal challenge for unfair dismissal and discrimination.
The academy told Ms Higgs she was dismissed "for reasons other than your religion".
It said the statutory rights of its staff were "not absolute".
It added: "We are concerned you did not demonstrate an appropriate understanding of the school's requirement to respect and tolerate the views of others and to role model such behaviour".
