Today I am thankful for work, not just my job (of which I am thankful for!) but for the whole concept of work. God gave us work as a blessing. Think about it, even in the Garden, Adam worked ... and he enjoyed his work there. It was a blessing, something to occupy his days and something to contemplate in the evenings. Sin is what has made work a toil. When we understand this and truly look at work in this perspective then we can say, yes, I am undoubtedly thankful for work to fill my days.
Work is not man's punishment. It is his reward and his strength and his pleasure.
