As smartphones and portable devices increasingly dominate our working lives, moves are afoot in France and Germany to prevent the little electronic miracle workers from encroaching on people's private lives as well.
For several years now, some of Germany's biggest companies have started waking up to the counterproductive effects of expecting executives to be reachable around the clock.
"Burnout" has become a buzzword in recent years as an explosion in the number of work-related psychological illnesses has forced companies to rethink the demands they make on employees.
The last three or four years have seen firms such as car giant Volkswagen install "virtual dams" to prevent the seemingly unstoppable deluge of workrelated e-mails from reaching stressed employees at home.
"The more work encroaches on people's private lives, the more employees are likely to suffer from stress, burnout and an inability to switch off," the German national institute for occupational safety and health, BAuA, found in a recent report.
Teleworking, or using IT or telecommunications to replace work-related travel or enable work outside the office, can be a valuable option for a company because it offers flexibility, said BAuA expert Frank Brenscheidt.
Leaving the office early to pick up children from school, and then finishing off the day's work at home, may suit some working parents.
But if it brings with it a permanent increase in workload and extra hours, "it can make some employees ill", Brenscheidt said.
According to the BAuA's statistics, the number of sick days taken as a result of psychological problems increased by more than 40 per cent between 2008 and 2011.
Volkswagen, at the behest of the mighty metalworkers' union IG Metall, has prescribed a daily rest period from work-related e-mails.
Its servers no longer forward e-mails to employees' work phones from 6.15pm to 7am.
Rival carmaker BMW has come up with a different approach.
"We are aware that a boundary needs to be drawn between work and private life. But we don't want rigid rules to negate the advantages of worker flexibility," said Jochen Frey, a spokesman for BMW's personnel department.
Since the beginning of this year, more than 30,000 employees can - in consultation with their bosses - carry out tasks offsite and outside normal working hours.
For example, an hour spent answering an e-mail request can count as an hour's overtime.
In 2010, the management of Deutsche Telekom decided that employees were no longer expected to be reachable around the clock. France Telecom adopted a similar initiative that same year.
France recently introduced a "right to unplug" for workers in the technology and consultancy sectors, where there are no set working hours.
The law effectively obliges workers to hang up their phones and portable devices at the office door.
But Bernard Salengro, a member of the white-collar union CFE-CGC, was sceptical as to "whether, or how strictly it would be applied".
For IG Metall, Europe's biggest union, some of the measures already introduced do not go far enough and, it argues, enforceable legislation is required.
Nevertheless in Sweden there is scepticism that a law obliging employees to "unplug" their work-related devices is the right way forward.
Martin Wastfelt of Sweden's largest white-collar trade union called for more pragmatism. "It's more effective to appeal to reason and explain to companies that it is in their interests to safeguard the health of their staff."
