"(1) It is unlawful to refuse a person employment - (a) because he is, or is not, a member of a trade union."
"(1) The applicant applied for a post as a Career Grade Social Worker with the respondent. His application was refused because of the respondent's experience of him when he was an employee of the respondent. The respondent had found that the applicant had an uncooperative attitude and an anti-management style.
"Your application has been carefully considered but due to our past experience of you as an employee when it was found that your confrontational and anti-management approach did not fit with the Kent culture we feel that there is an issue of personal "fitness" for the job. You have, undeniably, the necessary qualifications and experience but we will not be processing your application further."
"... part of the reasons for the Council's refusal to employ Mr Harrison were ... the Council's doubts about his suitability and "fit" for the post for which he applied (or for any posts within the Social Services Department) arising out of his perceived confrontational and anti-managerial stance. ..."
"... But we think that that is really putting it too blandly to be the totality of the Council's reasons, because the managers' perceptions of Mr Harrison's personality, and attitudes, and beliefs were absolutely conditioned by their view of him as a trade union activist and negotiator, particularly in regard to the strike, and in regard to his propagandist activities as publicity officer for the union. ..."
"... But it was the manifestation of his attitude, which, we are satisfied, both within and without the scope of his trade union activities, was indeed anti-managerial and confrontational, that decided the Council not to re-employ him."
"(1) For the purposes ofPart V of the Employment Protection (Consolidation) Act 1978 (Unfair Dismissal) 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) was, or propose to become, a member of an independent trade union, or (b) had taken part, or propose to take part, in the activities of an independent trade union at an appropriate time, (c) was not a member of any trade union, or of a particular trade union, or of one of a number of particular trade unions, or had refused to propose to refuse, to become or remain a member."
"An employee has the right not to have action short of dismissal taken against him as an individual by his employer for the purpose of - (a) preventing or deterring him from being or seeking to become a member of an independent trade union, or penalising him for doing so, (b) preventing or deterring him from taking part in the activities of an independent trade union at an appropriate time, or penalising him for doing so, or (c) compelling him to be or become a member of any trade union or of a particular trade union or of one of a number of particular trade unions."
"We find ourselves unconvinced of that distinction. In our judgment, the activities of a trade union officer in negotiating and elucidating terms of employment is, to use a prayer book expression, the outward and visible manifestation of trade union membership. It is an incident of union membership which is, if not the primary one, at any rate, a very important one and we see no genuine distinction between membership of a union on the one hand and making use of the essential services of a union, on the other.
"membership means no more than that a person has his name recorded in the union's register of members and holds a union membership card with the consequence that it is suggested ... "
"We have no objection to your being a member of a union, so long as you keep your membership card in your pocket unused and do not seek to make any use of your membership which could have any impact on us or our business."
"... at the least ... it is open to an industrial tribunal to hold that an employee has been dismissed for being a member of a union if he has been dismissed or penalised for invoking the assistance of the union in relation to his employment. To put it another way, in an appropriate case the tribunal of fact has power to be robust in its findings. ..."
