"I would hope that we could avoid such large strikes."
It's really easy to avoid. Just don't intervene in the free labour market.
Unions for both employees and employers have spent decades negotiating agreements on these things, and the last thing they need is some temporarily elected populistic politician saying "uh I think we need to change this so I can please my donors". Fuck right off with that. Since when did government overreach become typical right wing politics?
