"The respondent has produced no evidence which was not available at the time of the hearing and has raised no matters which were not canvassed at the hearing in some detail. In fact, by now producing written evidence from the gardeners, that it was common practice for them to have an 'unauthorised' tea break for a period of two years or so, does little to support the respondents' contention that, without any written embargo, it was appropriate to dismiss the applicant. It is of note that none of the statements by the other gardeners give any indication that they were aware of any serious oral warning having been given about the practice of taking unauthorised tea breaks until the events of1 March 1996 ."
