Why would you think otherwise? That literately describes 100% of company jobs (notice I did not add driving there) Every employee in America is only annoying their boss away from getting fired. Some companies make that real easy to do in the first 60-90 days by policy, some are anytime they annoy their boss they are gone. Ok yes, there is also the company went out of business route to get fired, but that just adds to the fact employees are not guaranteed a job.
Even union shops, it make take a bit longer to fire someone, but annoy the wrong boss and you can bet you will be written up for every little violation. After how ever many write up it takes, you'll be gone.
