What if we train our people and they leave?
What if we don't, and they stay?
The answer is Employment Bond, where the employee pays the company if they leave immediately after getting training. So for couples, a prenup?
For Father's day, I would suggest you plan at least a dinner with the family. Waiting for people to celebrate an event [birthday, anniversary, father's day, etc.], and they end up being busy for it or forgetting it can hurt. Sometimes initiating it yourself can save the pain, and works out for everyone. People do it for birthdays; "It's my birthday and I want to treat others". It doesn't have to always be a surprise or getting treated. For Father's day, you're a father, and want to celebrate fatherhood with your children/family.
For the relationship, I agree that it needs effort. Trust is important, investing in each other is important. Basically being there, and putting in the work, to make the relationship work is necessary.
Prenups don't work in Finland. But, they also only cover what people have come in with for the most part. The investment between might be a different matter.
In Finland, this is done in the workplace. people take a cake or a bag of candy or whatever to share on their own birthday, rather than expecting colleagues to remember.
Presence. People spend their attention on a screen, not on their relationships these days I think.
