ACAS has, today, published draft guides on discrimination on:
(a) sexual orientation discrimination; and,
(b) discrimination on grounds of religion/belief.
The guides are really, really good. They are not that long, and contain a comprehensive summary of the new law, worked case examples, suggestions as to what practices employers should follow or avoid, and a useful Q&A section. If you haven't read the legislation itself (and even if you have), these two documents are well worth reading.
