The requirement to report and publish trade union facility time (paid time off during work to carry out trade union duties) came in to force on 1 April 2017 for all public sector organisations employing more than 49 full time staff. This year, the deadline to upload your organisation's figures to the government portal is 31 July.
The government committed to developing guidance on facility time reporting, and over the past year has been seeking feedback from employers and trade unions to improve the guidance.
There is no official target in the legislation which states what the percentage of pay bill spent on facility time should be, but the government strongly encourages organisations to aim to reduce facility time spend to 0.06 per cent of their pay bill (the figure achieved by the civil service).
Read the guidance in full on the government website.
