Delays in Employment Tribunal
Data from 1st April 2020 to 31st March 2021 shows that on average, the time it takes from receipt of the ET1 Form to a first hearing (which might be a preliminary hearing; it does not mean disposal/final hearing of the case) is 355 days for single cases (made by a single employee/worker), and 388 days for multiple claims (made by multiple employees).
However, the Employment Tribunal seems to be making steps to try and improve this delay by moving to a new case management system and HMCTS is currently working on incorporating new IT systems in the tribunal.
