No ET3 submitted with PH in 6 weeks

R was informed during the internal grievance process that an unsatisfactory outcome would result in Tribunal proceedings.

R was informed of the same during EC and did Interact with ACAS during EC so cannot argue they were unaware of a claim being forthcoming.

Correct contact information was used when submitting the ET1.

The deadline for ET3 submission was the second week of November 2025. A PH is due to occur in the middle of April.

Claims made are Indirct discrimination, victimisation and constructive discriminatory dismissal.

Why would an ET3 not have been submitted?

What happens now? Apparently the ET1 is in with a judge regarding a potential rule 22 judgement; should I still complete a PH agenda to the best of my ability?
