it's all about pride. you should autograph your work with excellence.
Really, people go to work to earn a living, some enjoy their work, some hate it, but at the end of the day you want a wage, you wouldn't go for an apple and an orange at the end of the week...
I go to work and do my job, do I go over and above, no, not any more, I once did over and above my role and did additional work to assist the company.
We had a performance related pay scheme, I was awarded an "outstanding" score, my colleagues gained "met all", two scores lower...
I ended up with £200 extra for the entire year.
My time as a keen eager employee were over.
I now go to work, do my job , no more no less, I was recently asked about another role within the company getting an extra £10k a year, I turned it down because it would have likely increased my hours by a third, so I would have just ben doing extra hours for pretty much the same pay.
