The new world of work in Monaco
The COV­ID-19 pan­dem­ic and the meas­ures put in place in re­sponse in coun­tries around the world – in­clud­ing Monaco – have com­pelled both em­ploy­ers and em­ploy­ees to ad­opt a new vis­ion for work. Count­less com­pan­ies and gov­ern­ment agen­cies have sus­tained them­selves dur­ing the crisis by hav­ing em­ploy­ees con­duct their work from home.Now, months after the be­gin­ning of the pan­dem­ic, many of these meas­ures, such as home-of­fice re­mote work, have proven so ef­fect­ive they are be­ing con­sidered for the post-COV­ID-19 fu­ture. But re­mote work raises a host of leg­al and ad­min­is­trat­ive chal­lenges. This page – based on the 24 Novem­ber 2020 we­bin­ar The Fu­ture is Now: The New World of Work in Monaco and hos­ted by em­ploy­ment law­yers Soph­ie Mar­quet, Sylvain Ner­on and Florence de Guz­man with CMS Monaco – presents how tele­work and home-of­fice work have im­pacted the Mone­g­asque work­place, and ex­plores the chal­lenges that these forms of em­ploy­ment pose for work­ers and com­pan­ies, both now and in the years to come.
