The Greek government has defended its new six-day working week policy, saying it is an “exceptional measure” that would only be applied in “specific circumstances.”

Greece introduced in early July new regulation that gives employees in some businesses the option of working an extra two hours each day, or adding another eight-hour shift to their schedule — meaning they could work 48 instead of the traditional 40 hours a week. The policy does not cover food services and tourism businesses.

Outrage about the policy spread on social media as the regulation was met with backlash from labor unions and political observers criticizing the move. When the policy package containing the bill was first announced last September, thousands protested against the new policies.
