Ask HN: Do you code on personal/side projects during breaks at work?

I wouldn't recommend this unless you get written approval from your boss/legal dept/president, OR you leave the office for lunch and do your coding at a cafe/restaurant.

Many companies include language in the employee agreement stating anything you write on company time or company hardware is theirs.

Your employer will own your code if you do this.

To be more precise: you open up very serious IP ownership issues if you do this. It would scare most investors away very quickly.

Sleep earlier. Work on your own thing before you head in to your job. Take a couple weeks off for a workcation. Work on the weekends.

Yes.
