Grateful

We had a staff-day last week. A really good one, I might add!
You know, with team building exercises, various discussions about how to improve the workplace, bonding and in the end a well-deserved coffee break.

During one of the "team exercises" one guy said to all the others:
We should be more grateful. 
I have worked in other places and I can tell you it's so different.
Here they listen. We can suggest what we want to do on our staff-day, we can tell our ideas about how to work and they will listen to us. What we say matters.
....Guys, we should be more grateful.

Grateful.
Because at work your opinion matters.
Because your boss values your ideas.
Because someone actually listens to you.

I mean, gratitude is always a good thing...
