How often do you have to work on weekends?

It's definitely a regular occurrence, but more so when a launch is coming. We've got on next week and it's all hands on deck. Saying that, as long your team/management are aware of the work you put in and appreciate and value it - then it's worth it. I do think it's a balance and you do need to protect your mental health too and notice if it's being affected by working over weekends.
