The following table gives the percentages of workpeople directly involved in disputes involving stoppages of work, with the results, for Great Britain and North Ireland, 1918-27:— were generally small if the number of disputes only be considered, but very wide if the number of workpeople involved be taken into account. Thus, the number of workpeople involved in disputes that were settled by conciliation or arbitration varied from 1.2% to 68.5%; and the number involved in disputes settled by "other" methods from o•o% to 69.o per cent. This was a very exceptional case, in 1912, the great coal mining dispute of that year having been settled by legislation.
Whether, however, trade unionism tends generally to encourage or to restrain strikes, the organization and policy of the great majority of trade unions, as at present constituted, are based on the possibility of a collective withdrawal from work in the last resort. Dispute-pay is consequently the one universal form of trade-union benefit, and the strength of a trade union's strike-pay resources are among the factors which determine whether a dis pute will be pressed to a stoppage and, if so, how long the stop page, both sides proving recalcitrant, will last.
Although most strikes are controlled by trade unions, cases are comparatively rare in Great Britain in which the central commit tee of a trade union takes the initiative and directs its members to cease work. More usually a local strike movement is initiated by the local workmen, and the central committee is generally em powered by the rules to refuse its sanction to a strike and to close it at its discretion, but has no authority to order it. In many unions a ballot is taken of the members of the districts affected before a strike is authorized, and a two-thirds (or even greater) majority, either of members or of branches, in favour of a stop page may be required before the sanction of the central executive is granted.
When a strike has been authorized by the executive, the con duct of it is frequently entrusted to a "strike committee," ap pointed ad hoc, one reason being that a strike of any considerable dimensions often affects members of several unions, so that the common action necessary in a conflict with employers can only be attained by a committee representing all the societies involved.
The financial support of a local or sectional strike imposes but little strain on the resources of a large society, but where a con siderable proportion of the members are affected it is usual for a union to replenish its funds by imposing a "levy" or special con tribution on members remaining at work. Financial support is often asked and secured from other unions and loans from finan cial institutions such as the Co-operative Wholesale Bank, have become increasingly a resort of impoverished trade unions during a prolonged and embarrassing dispute.
