That’s crazy to me. Our manager went out on a boat last week on Friday, and we haven’t heard shit from him since. Hell, we’d probably tattle on him to our skip level if we did because our skip would be furious to hear people are working during vacation. I’m a software engineer in the US, and unfortunately stories like yours are all too common here :/
For my current job we’ve all agreed to take the approach of not writing comments that say what the code does, but why you did something the way you did. Probably about 90% of our code is uncommented because it just doesn’t need to be, but every once in a while you have to do something out of the ordinary to get the desired behavior, and explaining why you made the weird decision you did is infinitely more helpful.
