This claim will be vigorously defended. "Heather is baffled and hurt. These are unsubstantiated accusations." Sara - who says she was forced to work until midnight to dry Heather's hair after beginning her day at 7.30am - is also expected to claim she was intimidated by the charity campaigner, who demanded she keep silent about everything she saw and heard.The 24-year-old nanny, who resigned in September, lodged a constructive dismissal claim with an employment tribunal in Ashford, Kent, last week.In the complaint, Sara states her job had changed when she returned to work following maternity leave earlier this year.A source close to Heather insists the charity campaigner always treated her employee well, saying: "Heather gave Sara an awful lot of things. When Sara resigned, she got a car as a leaving present for goodness sake. She also paid for her to have private medical treatment. Heather is baffled and hurt. These are unsubstantiated accusations."Heather, 40, is expected to defend herself by saying Sara was employed as a housekeeper not just a nanny, and was showered with gifts, including a lavish holiday to thank her for her work and Beatrice's old clothes for her new baby.The two parties have 28 days to reach a settlement before the case goes to a tribunal.
