LISBON, Portugal (AP) — Portugal’s new law on working from home has grabbed attention around the world for the way it protects staff. Under the new rules, companies can’t attempt to contact their employees outside working hours. They must also help staff pay for their home gas, electric and internet bills. And bosses are forbidden from using digital software to track what their teleworkers are doing. There’s just one problem: the law might not work. Critics say the new rules are half-baked, short on detail and unfeasible. And they may even backfire by making companies reluctant to allow working from home at all.
