A layoff fundamentally changed how I perceive work

This hits me 2 ways, I got laid off in my late 30s and had over 4 years unemeployment. TBH, I'd got bored of what I was doing and it was looking like a career dead end. I took a hobby project and worked on that, learned iOS and eventually got a job in that.

But one thing got me, I developed an original app for the company I work for, that is now one of the focus products. I wish I never, I feel like it was literally stolen from me, never ever go above and beyond for a company, your managers will get the credit.

Why you think it's stolen when company paid for your time? If the app wasn't successful, would you have considered refunding your salary back to a company?

There's paying for someones time, and then there's going above and beyond. I feel like I shouldn't have gone above and beyond

And to throw it the other way around, when someone works over hours and contributes significantly, but burns out, does the company throw out the unpaid work?
