Don’t Get Fired - what’s the point of almost all the upgrades when work comes in so slowly?

While you can easily handle the workload without the later ugrades, you can get a lot of extra work when the president shows up. You can then work through the backlog once he leaves.

At a certain rank, you can motivate your team (anyone lower than you) to work faster. This costs health- more health means you can get faster xp and money this way.
