Honestly I feel like that might actually happen sooner or later. We currently have a government that bills itself as pro-labour and pro-lower middle class, and we're also about to start a round of collective agreement negotiations acrss almost every economic sector. The driver's and operator's union, aviation union and seafarer's union also threatened to strike in solidarity, and some of them did actually join the strike towards the end and the postal worker's union is... well, actually, it's kinda broke rn b/c the strike was long and extremely extensive, but going on strike in support of the other unions in the same labour sector is absolutely still on the table.

The splintering of the labour market, a lack of long-term stability, bad pay and zero-hour contracts is becoming an issue everywhere. Eventually, there will be a strike that is about that, almost exclusively, which will help set a precedent. PAU is also up and suing the company that I'm currently employed with for having me on a different labour agreement than the workers employed directly by Posti OY and Posti Palvelut OY. If that suit goes through, that will also set a precedent and better the labour rights of workers like me, even if we still can't get proper contracts with the mother company.
