The tribunal, which was sitting in Liverpool, ruled that the charity had not unfairly dismissed former regional volunteer support manager Jill Kershaw. She resigned from her role in December 2007, claiming that her treatment by the organisation had forced her to resign.
"I am delighted with the outcome as I have achieved what I set out to do, which was to show that Leonard Cheshire treated me abominably," said Kershaw.
The charity said the only ruling the tribunal made was that Kershaw was not unfairly dismissed.Colin Young, director of UK operations, said the organisation would not tolerate bullying or harassment of its staff.
"We have drawn up a detailed action plan with the staff association," he said.
"We certainly don't claim to be perfect, but the fact that we focus on the issue in our surveys, policies and management actions is an indication of the seriousness with which we view the matter."
