DLF settled the case just before it was due to begin on 29 March in Stoke.
Harris worked for DLF Trifolium from 1994, first as a marketing consultant and subsequently as a full-time marketing and communications manager, before being made redundant in February 2009, when DLF Trilfolium let five people go, including all three members of the marketing team.
The case that was to be put before the Employment Tribunal made claims around the Sex Discrimination Act 1975.
Harris said: "I am pleased with the outcome and hope that my actions will help to protect future employees."
DLF managing director Laurence Scowen said: "The case is resolved."
DLF Trifolium said before the case was settled: "We strongly contest the allegations that Mrs Harris has made and confirm that the company will be calling evidence which will rebut all of the claims that she has made."
