Masorti Judaism has become a Living Wage employer, following the lead of Liberal Judaism which was the first synagogue movement to sign up to the campaign at the end of last year.
Masorti marked its accreditation from Citizens UK's Living Wage Foundation at a Jewish study session at the movement's offices last Thursday.
Under the scheme, employers undertake to pay a minimum of £7.65 an hour nationally, or £8.80 in London. Hannah Bowers, worker for the Masorti youth movement Noam, said: "Throughout my 14 years in Noam I have been taught the importance of social justice. I have also been taught to realise how grateful I am for what I have.
"Every day I work hard, but it means a lot to me to know that another person who works hard - our cleaner - will now be paid a living wage. I want to congratulate all the Noamniks who have made this possible."
Fay Shum, area manager for Alpha Cleaning Services, which supplies Masorti HQ with its cleaner, said: "We know it is important to pay cleaners a decent wage, especially in London, where living expenses are typically high. Cleaners are often overlooked, but provide a valuable contribution service to companies and charities. It is very nice for once to feel our cleaners are appreciated and looked after."
