But there's some additional factors here. If the employer misses salary payments, then they're in breach of that employment contract, and unless they can't fix the situation really soon, that's grounds for immediate termination.

Also in Finland, salaries earned in a normal employment are backed by the state for up to 3 months of missed payments (the state will then try to collect from the employer). So it's relatively safe for an employee to stick with a sinking company. Just get that CV polished and start warming up the network.
