I own my own business so I can't speak for myself but I will for my husband. He values his job and watches as they change how they rank and evaluate workers. He wants to be seen as valuable, and he is.
A couple of years back, they asked him to run a plant in another state for ten months. He drove home (five hours) every weekend. One Sunday, we were heading to a historic theater in a big city to attend a movie premiere and he got a text that there was a big fire at the plant. He instantly left to go to the plant to oversee the situation. I wasn't surprised. He sees his role as part of his identity and it doesn't end Friday at 5pm. Sometimes the boss might send an email on the weekend and ask for some data calculations. It becomes his priority. His name has never been on the chopping block and he gets big bonuses and big raises...every year.
He considers himself blessed to have the work.
