There are so many songs from the labor movement that can easily be modified for the modern office environment, I’m sure your boss will love it.

🎵 Another day older and deeper in debt

or

🎵 My dad was an accountant and I’m an accountants son

🎵I stood nee deep in politics, got sick with a churning gut
🎵 I shoveled out the bullshit and it neigh on makes you chokes.
