The written proposal notably uses the phrase 'workers who menstruate', rather than referring to women directly

Zack Polanski's Green Party have refused to use the term "woman" in the group's new menstrual leave policy proposal, as the party continues to reject the landmark Supreme Court ruling on biological sex.

Leaked documents reveal the Green Party is weighing a proposal to grant "all workers who menstruate" an extra 36 days of paid leave annually.

The motion, submitted ahead of the party's Autumn Conference, would entitle employees to three days off each month during their menstrual cycle - without requiring medical certification.

However, the written proposal notably uses the phrase "workers who menstruate", rather than referring to women directly, according to The Spectator.

It comes more than a year after the Supreme Court delivered its unanimous verdict clarifying that "woman" in the Equality Act means biological sex.

Fourteen months on, and close to 400 public bodies across England and Wales remain in breach of the ruling, including widespread non-compliance among NHS trusts, police forces, local authorities, and Whitehall departments.

Green Party leader Zack Polanski is said to have fostered a "hostile environment" for those with gender-critical views, with gender-critical campaign groups accusing the party of orchestrating a "witch-hunt" against its members.

Under the proposed menstrual leave policy, time away from work would neither count as sick leave, nor be subtracted from existing holiday entitlement.

Those with conditions such as endometriosis, adenomyosis, or polycystic ovary disease could receive additional time off even beyond the proposed three days, with medical documentation required just once per year.

The proposal was put forward by Allan McLeod, a male member who represents the Darlington Green Party as a trade union official.

Mr McLeod has also served on the party's National Disciplinary Committee, with his social media activity suggesting he is an active supporter of trans rights.

If adopted, the policy would be incorporated into the "Workers Rights and Employment" section of the Greens' "Policies for a Sustainable Society" document.

A Green Party spokesman cautioned that the conference remains several months away, and the disclosed details of a menstrual leave proposal are not set in stone.

The spokesman said: "Conference is still months away, and although members have started to submit motions, not everything submitted ends up being discussed."

The party's annual gathering is scheduled for Brighton in October, where members are able to debate the menstrual leave policy, among other proposals.

Among the floated motions surfaced in recent weeks are a call to prohibit male circumcision for children, and a declaration that "Zionism is Racism".

Internal divisions within the party recently emerged over antisemitism, with leader Zack Polanski facing criticism from groups such as the Global Majority Greens.

Meanwhile, the party’s Health Policy Working Group launched a consultation to determine whether parental consent for circumcision on Jewish infants should only be mandated on grounds of medical necessity.

The body also contests whether "non-therapeutic male circumcision should only be performed on children who are old enough to make an informed choice".

As with any proposed policy, a Green Party spokesman stressed members work autonomously on policy exploration and formation projects, adding "this is not party policy".

"The only way for anything to become party policy is through a vote at conference."
