What professions or people are under-appreciated?

Anyone who cleans up an environment for work (or even eat home).  It seems easy for people to just take for granted that the cleaning gets done.

It almost seems like they get looked down upon by many members of society, but they have to multitask a lot of things so that people can get their food.  It also seems like some people feel justified in yelling at them if food comes out wrong or less than perfect.

I definitely appreciate them way more after being forced to do self checkout a few times!

As someone with a terrible sense of direction and a dislike of driving, I'm grateful for delivery.  I think the pressure and problems they deal with when there is a mistake is underestimated.

They do a lot to help people in bad social situations.  They provide more value than the pay and recognition would indicate.

They are frequently made fun of and people don't like them driving behind them, but they are the first called in an emergency.  I'm grateful for the officers who have helped me.
