She was an elected Poor Law Guardian in Manchester. Katherine and four other women were employed by the North of England Suffrage Society in the summer of and autumn of 1900 to gather signatures from women cotton mill workers for a suffrage petition to Parliament. They gathered over 29,000 signatures and the petition was presented to a small number of sympathetic MPs in the House of commons on 15th March 1901. Katherine, Esther Roper and 15 cotton workers accompanied the petition to London.
In July 1902 Katherine and other radical suffragists worked hard to raise the issue of women’s suffrage during a parliamentary by-election in Rossendale in which the Labour Representation Committee candidate was David Shackleton, President of the Darwen Weavers’ Association. They pointed out that women weavers (who were majority in the various weavers unions in Lancashire) were supporting his candidacy and Labour MPs with their union subscriptions, but did not have the right to vote themselves.

When they did hold a ballot, the result was “yes”.
The North of England society now concluded an agreement with the Central Suffrage Society, who agreed to pay the salaries of speakers to visit other industrial areas and speak to women workers . Katherine, along with Mrs. Green, Eva Gore Booth and Esther Roper addressed over one hundred meetings, peaking to meetings of pottery workers in the Midlands and hosiery workers in Leicestershire.
On 11 October 1904 she resigned from the MSWTUC along with Christabel in support of Sarah Dickenson and Eva Gore Booth.

In late 1905 Katherine, Esther Roper , Eva Gore Booth, Sarah Dickenson, Christabel, Pankhurst and others resigned from the Executive Committee of the Society and now pursued their campaign through the Lancashire and Cheshire Textile and Other Workers’ Representation Committee of which Katherine was an active member and on the Committee.
In late 1909 she was one of a group of radical suffragists who went up to Rossendale during a parliamentary by-election to campaign on belaf
