Working continuous overtime is one of the worst diseases you can inflict upon your company.<p>1. By making changes outside of work hours (comitting code as a software dev), you're upsetting your teammates understanding of the state of the project. Ever had on-call push a 200+ LOC change after hours to hot-fix a bug, then had to have a two hour meeting next morning to figure out what changed and how to re-do the fix properly? When you make changes outside of hours, you put your teammates into that position every time.<p>2. You upset your teams and your companies understanding of their capacity. Because you are not beholdent to work overtime by the contract, if you decide to take a break from overtime for whatever reason, projects will start slipping with no perceptible root-cause. This is a really bad spot to put your team into.<p>3. You're likely to become the "rockstar". This isn't necessarily a bad thing, but can be damaging to companies that do not now how to work with them - see <a href="https://neilonsoftware.com/difficult-people-on-software-projects/developers/the-rockstar" rel="nofollow noreferrer">https://neilonsoftware.com/difficult-people-on-software-proj...</a>.<p>4. You will eventually start burning out, there's no question about it. Burn out doesn't affect just you, it affects the company. Once you start burning out, all sorts of interpersonal and quality problems will develop that will jeapordize a (hopefully) otherwise healthy team.<p>5. You will ocassionally ping your teammates outside of work hours, some of whom, due to various reasons, will feel a need to respond, or "hop on for a quick check". Yes, the teammates are in control of their actions, no, that does not excuse you from regularly pinging them outside of work hours. This is especially nefarious if there is a power imbalance, such as a more senior engineer (or a rockstar) pinging a more junior engineer.<p>If you're finding that you need to continuously work overtime to meet deadlines, speak with your manager, this is a problem for them to solve, not you.
