The Employment Tribunals Service confirmed this week that it had received claims against the YWCA from Annetts and Jane Whittle, former London and south east regional manager.
Annetts quit the charity last year after three months in charge amid claims of a disagreement with the board over the future direction of the organisation (Third Sector, 7 November 2007).
Whittle, who was made redundant by the charity in 2007, has submitted a claim of unfair dismissal and sexual discrimination. Both claimants were unavailable for comment.
A spokeswoman for the YWCA said: "YWCA is aware of the claims and will respond in due course.
"YWCA is committed to enhancing internal procedures and practices and takes action to ensure staff are treated fairly."
