The Families and Work Group manifesto contains steps the government chosen in the 2015 general election should take to ensure fairness in the workplace through policies and best workplace legislation.
They include appointing a cabinet-level, cross-departmental minister for childcare, in recognition of the important part good childcare has on economic and business success as well as the welfare of employees.
It also calls for workers to have access to periods of "adjustment leave" – designed to enable families to deal with short-term crises such as serious illness to a child or partner.
Working Families director of policy, research and communications Julia McCarthy told HR magazine Working Families wants to highlight the issues that will "make the most significant difference" to employees.
"We want one strong, cohesive voice," she said. "There's so much more government can do to improve the workplace for families in work. We're also hoping big employers embrace the suggestions made."
