"The union reminded us that 'compatible' means 'consistent' or 'able to co-exist with'. That is, we are not required to decide on the most effective form of management, merely that what we decide is compatible with effectiveness. Or, to put it another way, we need to examine whether the union's proposed bargaining unit is found wanting and does conflict with effective management."
"However, while I accept Mr Bowers' submissions on this aspect of the case, I do not agree with his related submission that the CAC must choose the most appropriate bargaining unit on the evidence before it. On the face of it, this is a perfectly cogent submission. Indeed, it seems perverse to conclude that the CAC is entitled to determine, as the appropriate bargaining unit, a less rather than more appropriate unit. But in my judgment what is most appropriate depends upon the particular context in which a determination has to be made. The CAC is not engaged in an abstract exercise of deciding how in an ideal world it would map out a company's bargaining arrangements. It is faced with a specific claim for recognition which the employer has already rejected. The employer's opposition may be to any bargaining; sometimes it will be to the particular bargaining unit selected by the union. But the employer's opposition must seriously engage the union's proposal if it is to carry any significance. If the employer is going to suggest an alternative bargaining unit it must be one that would at the very least be capable of regulating the terms of a significant proportion of the workers in the union's proposed bargaining unit. To take an extreme example, it is obviously no answer to a claim for recognition in Bolton that there is a more appropriate bargaining unit in Liverpool. That simply does not meet the union's claim that it should represent a group of workers who want their pay, hours and holidays determined by collective bargaining, and it does not meet the concerns of these workers. 50. If the CAC were to have to determine the most appropriate bargaining unit, independently of the context in which the issue arises, it would in many, perhaps most, cases be reaching a decision of no value which could, moreover, frustrate the statutory process. The company will often be able to suggest what everyone would agree would be, if it could be implemented, a more desirable bargaining unit to that proposed by the union, while of course being unwilling actually to recognise any union in respect of its proposed unit. For example, unions will often pursue recognition following a concerted membership campaign in a particular geographical area or company division. It can hardly have been Parliament's intention that it should fail in its recognition ambitions simply because the employer was able to conceive of a better starting point for collective bargaining, such as recognition nationally or on a regional basis, or through plants rather than divisions. Of course, the position would be otherwise if the union's proposals were not compatible with effective management."
