In 2017, Antti Rinne provoked some controversy by encouraging Finns to reproduce.[12]
Antti Rinne was convicted of organizing an illegal strike with the trade union Pro against the forest industry. The conviction was upheld by an appellate court with an additional decision at the end of 2018 which also ordered Rinne to pay fines and legal costs to Metsäteollisuus, and advocacy group for the forest industry.[13][14]
Rinne had to resign from an ACP (Automotive, Cargo and Ports worker's union, Finnish: AKT) lawyer position, because he had charged twice for the same work-related commute. According to him, it had been the result of negligence and amounted to only about FIM 1,000 (€200). In 2005, the President of the ACP stated in an interview with the Suomen Kuvalehti that it was actually FIM 10,000 (€2,000).[15]
In a second court case discussed, Rinne was the manager of a housing company in Lohja, Finland. The Suomen Kuvalehti reported that he had failed to return the receipts for the year and had paid for his own telephone bill from the housing company's bank account. FIM 25,000 (€5,000) of damages were claimed from him by the housing company.[16]
In 2022, Rinne applied for the position of Mayor of Lohja. Rinne's party has had a long history of governing Lohja, but 2022’s election results shifted the city council to the right. The city council started deciding on the next mayor in May 2022. The mayor's selection group was led by Joona Räsänen [fi], but he recused himself, as Rinne is his godparent.[17]
