I propose that the conditions of the right to strike be standardised, either by law or by amending all collective agreements, along with the right to a cash wage replacement for the duration of the strike. The condition could be uniform in roughly this form:
For the duration of a strike at the employer's premises, organised in accordance with the law, which is the result of a serious violation of the employer's workers' rights, workers shall be entitled to compensation equal to 70% of their basic salary. The compensation is limited to a maximum of 3 working days. There would be no change in occupations where strikes are not allowed.
 
Reasoning:
The right to strike is protected by the Constitution (and is not diminished by the proposal), but varies widely between collective agreements; in some collective agreements it is regulated in a similar way to the proposal, in others - especially in public sector collective agreements - the conditions for strike action are loosely stated and these employees are entitled to 100% wage compensation for the duration of the strike, which is wasteful, unconstructive, does not lead to a quick settlement of disputes, but results in frequent and sometimes unjustified strikes, and is also controversial in other sectors because of the greater rights. Examples include the Collective Agreement for the Education Sector, the SKEI, and arrangements abroad, where strike action is also regulated very differently - e.g. in Switzerland, during a strike, the employment contract is frozen, and thus employment rights, whereas in New Zealand, the employer has the right to reduce wages for strike action by the amount of work not done, or a flat rate of 10% per month when the worker has been on strike.
The proposal could also be amended, but it should follow the principle that a worker whose contract of employment is more seriously breached retains the right to strike, that all professions have equal rights in this area, and that the arrangements do not encourage frequent, unjustified strikes and unjustified use of employer or public funds.
