Ok, assuming I have to tell them, any thoughts / ideas on how to approach this conversation with my manager? HR? Not applicable because you aren't required and should not tell your employer. Some things to know when moonlighting: * Don't work for your employer's competitors or vendors. * Don't moonlight if you're here on a visa. * In CA your employer can't forbid you from moonlighting, but you can always be fired for any reason (for ex: poor performance) so just make sure moonlighting doesn't get in the way of your salary employment. * Don't tell your employer, they have no right or reason to know. Do you ask permission or notify your employer before taking a weekend trip to Tahoe? No of course not, so don't ask/notify them when you do anything else on your own time. I verified all this before starting a side-project back in 2013 after work and on weekends (wakatime.com/about)
