And, according to the country's government, it was.
On Tuesday, the official Twitter account for the government of Finland issued a statement refuting the report.
The government explained that Prime Minister Sanna Marin "envisioned the idea briefly in a panel discussion last August."
In the Finnish Government´s program there is no mention about 4-day week. Issue is not on the Finnish Government’s agenda. PM @marinsanna envisioned idea briefly in a panel discussion last August while she was the Minister of Transport, and there hasn’t been any recent activity.— Finnish Government (@FinGovernment) January 7, 2020
At the time, Marin was the Minister of Transport.
"There hasn't been any recent activity," the statement concluded.
In her previous comments, Marin said it would allow Finlandians to spend more time with their families and enjoy hobbies.
