"an Industrial Tribunal shall not determine whether a dismissal is fair or unfair if at the date of dismissal the complainant was taking part in ... other industrial action."
"Obviously an employee is not participating in a strike simply by indicating that he will strike at some date in the future. But he is participating once he indicates that he will refuse to work when called upon to do so even if he is not then required actually to work."
"It seems to us that Mr Lewis was indicating on behalf of himself and his colleagues that as long as the dismissal stood they intended to withhold their labour as from the following day, Tuesday 18 December. We think that thereafter they were taking part in strike action or other industrial action. They were collectively withholding their labour in order to put pressure on the employer to change the decision which he had taken with regard to two of their colleagues."
"Moreover, it is not entirely clear whether one individual by his actions can "trigger" the section; or whether it applies only to collective action."
"It seems however that there must be conduct designed to coerce the employer to improve the existing terms and conditions in some way. Having reviewed the evidence we are satisfied that on the evening of 17 December while in the yard, Mr Britton made it clear to Mr Mason that he would only go to Scotland if he was paid£15 overnight allowance...
"We do not consider that Mr Hillier [Counsel] is correct when he submits that the only person who can take part "in strike action or other industrial action" is one who withholds his labour when he is contractually due to work. If, for example, in a particular case all the employees of a company which is engaged on a three-shift system of work meet and decide that as from the time of their meeting they will all stop work, we do not consider that the only ones who are taking part in strike action or other industrial action are those whose shift is due to work at the moment of the decision. It seems to us that those employees who are due to work on the next two following shifts are taking part in strike action or other industrial action when they intimate that their labour will be withdrawn at a time when the current shift actually stops work. They do not only begin to take part in strike action or other industrial action when the time of their shift comes and they do not actually work."
"But in the end this is a question of fact for the tribunal, and we do not consider that in the particular circumstances of this case it can be said that they came to a conclusion which was perverse."
