"In our finding therefore, the relationship between these parties was brought to an end by the applicant's failure to exercise her statutory right to return at the end of April 1991. It does not seem to us that there was ever a dismissal by the respondents of the applicant at all. By September 28 1991, when the Originating Application was presented, the applicant had not exercised and was not entitled to exercise any right to return to work either statutorily or contractually and in our finding therefore she had not been 'dismissed' within the meaning of the Act at all. We therefore find that a Tribunal has no jurisdiction to entertain her application, which is dismissed."
