"In completing their assessment of Mr Dundon, the assessors were asked to make due allowance for reasonable time off in connection with trade union activities. They have been guided in their interpretation of reasonableness in this respect by Mr Mackintosh's letter (of30th January 1990 ).
"They did not select him because he was a union activist, though his union activities were relevant to his selection as we shall see."
"The arrangement (in the letter of 30th January) became a dead letter. The respondents were not reasonably entitled to resurrect it for the purposes of his assessment for redundancy. The feature of the applicant's working life that made the respondents select him was that he did not spend nearly enough time working for them, that he devoted far too much time to trade union duties (though the respondents were not hostile to his trade union duties as such). But they had helped to allow the position wherein he was spending too much time on union matters to develop from the situation stipulated (in January 1990). They should not have measured him against the standard implied in that letter."
"Where the reason or principal reason for the dismissal of an employee was that he was redundant, but it is shown- (a) that the circumstances constituting the redundancy applied equally to one or more other employees in the same undertaking who held positions similar to that held by him and who have not been dismissed by the employer; and (b) that the reason (or if more than one the principal reason) why he was selected for dismissal was one of those specified in section 58(1)."
"For the purposes of Part V of this Act, the dismissal of an employee shall be regarded as unfair if the reason for it (or if more than one, the principal reason) was that the employee- (a) ..... (b) had taken part or proposed to take part in the activities of an independent trade union at an appropriate time, or (c)........
"A reason for dismissal of an employee is a set of facts known to the employer, or it may be beliefs held by him, which cause him to dismiss the employee."
