This is not legal advice, and it was not written by a solicitor.
I run operations. I have built compliance systems inside businesses, and I have read the guidance carefully and cited it throughout. That is not the same as legal advice and I am not going to pretend otherwise.
If you have an employment solicitor you can call, you do not need this. Call them. They will do it better and they will carry the risk, which is worth considerably more than the fee.
If what you want is a summary of the law, the EHRC and Acas both publish one free, and both are better than anything I could write. They are listed at the bottom of this page and you should read them regardless of whether you buy anything here.
This kit exists for the gap in between: you know you need to do something, and nobody has told you what the folder is supposed to contain, in what order, or how you would show it to somebody who asked.
Corrections. If something in it is wrong, tell me. I fix it and reissue to everyone who has bought it, free, for as long as the product exists.
