I'm thinking of switching jobs cashing out my old 401k and using it to pay off some debts
What kind of debts do you have?
I have a mortgage on my house and a new laptop.
It is good to pay off your debts. After you pay debts off you should also continue to save for the future when you might need money again.
I'm not going to tell my employer about my debt and I'm going to use the 401k to pay it off.
You don't need to tell them what you're going to use your 401K for. It's good as long as you use it for something useful.
