The Trade Union (Facility Time Publication Requirements) Regulations 2017 came into effect on the 1st April 2017.
These regulations place a legislative requirement on relevant public sector employers to collate and publish, on an annual basis, a range of data on the amount and cost of facility time within their organisation.
The data is required to be published on a website maintained by or on behalf of the employer before 31st July each year, and within the annual report.
The Cabinet Office published supporting guidance on 2 June 2018 which has clarified the data which should be disclosed within the annual report and accounts.
