My team is under no obligation to keep up with me, but Im not going to lower my performance for them.
I'm not going to pass judgement here, as it's a complicated issue and I have zero context, but I hope you understand why this is not an entirely truthful thing to say.
Working over your vacation sets a tone whether or not you intend it to.
I'm asking because I tend to dive into work headfirst. I love doing this stuff and I can't believe I'm getting paid for it; but if this is a thing perhaps I should be a little quiet about that - I'm not interested in making enemies of people by being 'too peppy'.
Yeah sure - most metrics in software do not work as expected, so the only thing that we are left is perceived performance. And perceived performance is created only by comparison - You always subconsciously look for the baseline observing people in Your team, so if one ot them is concentrated only on work and is at least a little bit competent while doing it, it makes others look worse in comparison.
