"What does ‘women only’ mean?
GWL recognises that women can thrive and foster skills and knowledge in spaces which are orientated around women and their lives and experiences. We also seek to redress sexism, discrimination and misogyny by promoting the lives, work, histories and achievements of women from a range of backgrounds. For these reasons, some of our events, classes and workshops are for women only, and sometimes are targeted at specific groups in particular, for example Muslim women, Women of Colour or younger women.
All women-only opportunities and events are inclusive of Trans and Intersex women, as well as non-binary and gender fluid people who are comfortable in a space that centres the experiences of women.
GWL is sensitive and inclusive of all gender and sex identities, and we recognise the complexity and limitations of language that can occur when describing gender specific events. As such, our women-only statement will be reviewed regularly.
All women only classes, workshops or events will be marked clearly in our print programmes and online."
