There's a fairly gloomy thing called (I think) something like 'Gonna go to work on Monday one more time", which is largely about a bloke whose been killed off by his job. For a more cheering song, again, not sure of the title, but the chorus goes....

I'm looking for a job with a sky high pay A four day week and a two hour day, Maybe its because I was born that way, But I never did like being idle.
