The 5 worst downsides based on the given context are:

1. Lengthy and Complex Dispute Resolution Process
   If a mixed committee does not make a decision within 30 days, the issue must be brought before an arbitration tribunal, which then has six months to render a final decision. This multi-step and time-consuming dispute resolution can delay problem-solving significantly [1].

2. Strict Restrictions on Service Providers’ Entry and Residence
   Service providers from third countries must already be integrated into the regular labor market of their home member state for at least twelve months before they can provide services in Switzerland. This restricts mobility and access for service providers [2].

3. Limited Duration for Service Provision by Posted Workers
   Workers sent by a service provider from another member state can only provide services in Switzerland for a maximum of 90 actual working days per calendar year, limiting the ability to engage in longer assignments [3], [4].

4. Risk-Based Control and Notification Procedures
   Switzerland can impose a notification period of up to four working days and conduct on-site controls in specific sectors based on its own risk analysis. This can create uncertainty and administrative burdens for service providers and employers [4].

5. Non-Regression Clause Protecting Swiss Standards Limits Flexibility
   The non-regression clause prevents Switzerland from lowering its labor and employment protection standards post-ratification, which could limit the country’s ability to dynamically adapt or reduce regulatory burdens in the future [5].

The contracts do not contain specific information about potential disadvantages of the new framework agreement for an average Swiss family. They focus primarily on legal and economic framework conditions, as well as rules for services, labor, control, and cooperation. Concrete impacts on average families are neither discussed nor detailed in the agreements.

The texts emphasize Switzerland’s access to EU programs like Horizon Europe and Erasmus+, highlighting the importance of international collaboration for maintaining competitiveness in research, innovation, education, and mobility of individuals. Issues such as administrative burdens for participation in third-country mode and the consequences of non-association are addressed mainly in terms of research, innovation, and institutional cooperation rather than personal or family-level effects [1].

Further, social security coordination principles are updated to protect social insurance rights of EU citizens in Switzerland and vice versa, ensuring no discrimination based on nationality with regard to mobility under these programs. However, these pertain mostly to labor market and social security regulations without explicit reference to family-level disadvantages [2].

Overall, the agreements and commentary focus on systemic economic and institutional benefits or challenges—especially for actors like researchers, educational institutions, companies, and the Swiss economy—rather than direct implications for individual families [1], [2].
