"I was disappointed to hear that you expected the matter to end up in the hands of a solicitor and would be grateful if you would confirm that you will be returning to work at the end of your current sickness on the basis described above.
"16 In relation to this issue we find that the applicant's letter of15 August 1995 constituted a clear expression of her intention to return to work, this in response to a request from her employer asking that she confirm her intention to return. The applicant's letter of 18 August advised that she would not after all be returning to work due to ill health. This letter amounted to notification that Mrs Corfield would be taking a period of sickness absence and was not an extension of her period of maternity leave. The latter had effectively been ended by her letter of 15 August confirming her intention to return to work on 21 August. The letter from Mr Watson of 25 August gave details of the job which Mrs Corfield would have "at the end of (her) current sickness" and clearly indicated both that he recognised that her absence from work was due to illness and that he regarded her employment as continuing. We therefore find that Mrs Corfield's employment did not come to an end on18 September 1996 and that the respondent's letter of that date amounted to a dismissal."
"21 The final question for us to consider is whether the applicant had been discriminated against on grounds of her sex, that is she was treated less favourably than a man would have been treated. In that respect we have had regard to the decision of the House of Lords in Webb -v- EMO Air Cargo (UK) Ltd[1994] IRLR 482 . As noted above the respondent used the expiry of the period of 4 weeks after the applicant's notified day of return as an excuse to regard the applicant's employment as having been terminated. That is not a basis on which a male employee could have been dismissed. In accordance with the decision in the House of Lords in James -v- Eastleigh Borough Council[1990] IRLR 288 discrimination arises when "but for" her sex, a woman would not have been treated less favourably than a man in similar circumstances. There is no need for the applicant to prove the reason for the treatment complained of was an intention or desire to discriminate and, conversely, the absence of such an intention or desire will not excuse a person who otherwise commits an act of direct discrimination. The fact that Mr Watson did not intend to discriminate against Mrs Corfield on grounds of her sex does not therefore any defence. Because Mr Watson chose to dismiss the applicant for a reason related to her pregnancy he was treating her less favourably than a man in similar circumstances and therefore discriminated against her on grounds of her sex contrary tosection 1(1)(a) of the Sex Discrimination Act 1975 ."
"... when an employee had lost her right to return to work any contract of employment is emptied of all useful content and as a matter of common sense as well as law comes to an end, in the absence of express agreement to the contrary."
