It is the work ethic and like both
@SmokinM and
@BFE said, common sense and don't tear things up. US "old people" also will do what needs doing even if it isn't in the "job description" and won't stand around doing nothing waiting to be told what to do next. It is the showing up when we say we will, it is not being on drugs, or smoking dope, not being drunk, and caring about someone else's equipment or property instead of the "oh well, it's not mine" attitude.
I have dairy farmers that have accommodated my limits with the knees and ankle over the past several years because they say that I am honest and a loyal worker and they can count on me to do what I say. Many send me to the house to do the computer work and never think twice about it... I would no more go through their stuff or steal from them than I would from my best friend. Many say that they don't want to go through 5 new milk testers to try to get one that will do the job and do it right. I may not work as fast as I did, but I learned how to work more efficiently so that I do not hold them up in the parlor and we still get done in a timely manner.
They worked with me when I had the ankle done and was in a boot and non-weight bearing on crutches.... carry the milk meters in and out of the parlor and set them up. They have done the same as the knees got to the almost intolerable pain levels. Now that the knees are done, I hope to be able to go back and test a few more years. The good thing for me is that with the farms selling out over the years it is no longer full time so I am not as pushed to work so many farms, as I was. I want to do a little less....and enjoy my own stuff a little more.
But I had a farmer said that if I quit testing, did I want to come and work part-time on the farm; even just during hay season raking hay and stuff....
Be proud of what your work ethic has shown you to be a good reliable employee.... yeah, accommodating a few health problems or limitations is small stuff nowadays when so many are too da#@ lazy to get out of bed.....
