I know I’m going to be downvoted but it might really depend on the company. When I took on more than I should it was because I saw a need and it wasn’t a problem for me to do it. I ended up getting a cash award and a promotion. My manager also told me never discount how much and far personally goes in the workplace. She was the one who recommended me for the cash reward too, but she also wrote the most glowing recommendation I’ve ever received and my new boss said they’ve never read a recommendation mostly focused on what a kind and empathetic person I was and it was refreshing to them, and also put me over the other candidates trying to get a job. For reference I work in biotech so this isn’t minimum wage/entry level work. I did start out in entry level but I didn’t work more than I had to lol.
As someone who quit a job because my life was miserable working with miserable people- being really nice is a treasure and it radiates out beyond what you may think. I hope people who are unkind find a job that makes it easier for them to be kind because it really brings the energy down working with people who aren’t nice because they hate their life/job
