James Noble, the managing editor of Working Partners, responded to the complaints at the time by writing: “The worlds created by Erin Hunter are meant to be inclusive for all readers and we want to let you know that Gillian Philip will no longer be writing any Erin Hunter novels.”
Philip, who took the firm to an employment tribunal last April, is hoping to appeal the ruling which fixated on her “worker” status in Edinburgh.
Shah Qureshi, a partner at law firm Irwin Mitchell and Ms Philip’s legal advisor, said: “Non-traditional employment relationships are now commonplace, and it is important that those working under such arrangements, like Gillian, get the same protections as others.

“This includes the right not to be discriminated against for one’s beliefs.
“There are many workers in publishing and the creative industries with unorthodox working arrangements who nevertheless have mutual obligations with their employers akin to that required to be classed as a worker or employee.”
HarperCollins UK distanced itself from the row and that it had no contact with the author.
A spokesman said it had “only an arrangement” with Working Partners.
Working Partners said in a previous statement that “Gillian Philip had associated the Erin Hunter pen-name with her personal views on Twitter, thus associating them with the whole collective” and that “the decision taken was not in direct response to the nature of Gillian’s personally expressed views”.
