I totally agree with this. This culture of being expected to be present at work simply to pretend like you're working more needs to end immediately in every work place. It's just plain toxic.
4 basically means don't be that guy who does as little work as contractually obligated to.
There was actually one situation where I was the last to come and first to leave. I'm pretty sure I was well disliked at that company even though I more than did my share. You're just not seen as part of the group.
Not necessarily - if things need to be done, don't leave people to it just because you're done; try to be helpful (of course don't let others take advantage). The same way - don't stay over time if given thing can be continued next day; work is work, and while it is important, there are more important things
Only if 100% of your co-workers over-work, arrive early and stay late. I’ve worked in companies of wildly varying sizes, from 2 (startup) to 200,000 (megacorp), some of them full of very hard workers, and it has always been easy to not be first out by just meeting the minimum time obligation that I agreed to. There are usually some people working less, and the advice above was just to not be one of them, rather than kill yourself by working harder than everyone.
If that means I’m not liked, I’ll pay that tax.
