Former Chelsea doctor Eva Carneiro's constructive dismissal case will go to a full tribunal hearing later in the year.
The preliminary hearing on Wednesday between Carneiro and Chelsea ended with both sides unable to reach an agreement.
No date has yet been set for the full hearing, but it is likely to be at the beginning of June.
The private preliminary hearing took place at the London South Employment Tribunal in Croydon before a senior employment judge. It lasted three hours and Mary O'Rourke QC, who represented Carneiro, confirmed afterwards that no settlement had been reached.
The terms of reference for the full tribunal were agreed at the hearing - the list of witnesses and the evidence that can be disclosed, such as emails and texts.
Carneiro's legal team want her re-instated in her position and also want personal injury compensation. Chelsea filed their defence in the case last month.
Carneiro also has a separate personal legal action against former Chelsea manager Jose Mourinho, who left the club in December, for alleged victimisation and discrimination.
Carneiro, 42, was dropped from the Chelsea bench by Mourinho after she and physio Jon Fearn went onto the pitch to treat Eden Hazard during the 2-2 draw with Swansea at Stamford Bridge on August 8.
The action meant that Chelsea were temporarily down to nine men against Swansea, and afterwards Mourinho called Carneiro and Fearn "impulsive and naive".
Carneiro did not appear on the bench again for first-team duties and parted company with the club in September.
Mourinho was cleared of using discriminatory language towards her following an investigation by the Football Association. Afterwards, Carneiro and the FA's independent board member Dame Heather Rabbatts criticised the governing body for not interviewing the doctor as part of its investigation.
Carneiro made no comment as she left the court with her husband. The couple entered a waiting taxi outside the building as they were surrounded by photographers and cameramen.
