Out-of work actors, public relations experts and watchmakers looking for new jobs in their fields are set to get favoured treatment under a new Swiss system of hiring preferences that takes effect in July.

Non-EU member Switzerland adopted the scheme to help mobilise labour at home than curb immigration from the European Union, as voters had demanded in a binding 2014 referendum.

Brussels insists that EU citizens must be able to live and work in Switzerland - whose population is a quarter foreign - as the price for enhanced Swiss access to the EU single market, the biggest for Swiss exports.

Alongside actors, public relations experts and watchmakers, the current list includes some categories of farm labour, telephonists, reception staff and housekeepers.

The new Swiss system approved by parliament in 2016 headed off a direct clash over immigration and is now being rolled out. It gives people registered as jobless in Switzerland first crack at open jobs in sectors with above-average unemployment.

The government approved on Wednesday the list of categories that fall under the scheme because they have jobless rates of 8 per cent or more, a threshold set to fall to 5 per cent from 2020.

The overall Swiss jobless rate stood at 2.7 per cent in April.

The economy ministry will determine each year which job categories qualify for hiring preferences based on average nation-wide unemployment rates they show over 12 months.

Alongside actors, public relations experts and watchmakers, the current list includes some categories of farm labour, telephonists, reception staff and housekeepers.

Even though the new hiring system averted a diplomatic crisis, Swiss-EU ties remain fragile as the sides try to negotiate a treaty that would put relations on a firmer footing. A patchwork of 120 sectoral accords now governs ties.

Most Swiss support the government's plan to forge a new treaty that would have arbitration panels to help settle disputes, a poll published last month showed.

While arbitration could take the edge off Swiss reservations about giving the European Court of Justice a role in settling disputes, differences over state aid and Swiss measures to shelter domestic labour remain potential stumbling blocks.

The two sides aim to wrap up negotiations this year, but any deal faces Swiss voter approval under the neutral country's system of direct democracy. Parallel EU negotiations with Britain over terms of its EU exit also complicate matters.
