Conceal a surveillance camera. You want a time stamped record of your hours working at your desk. This will throw some water on the staged or fake rape that some careerist cabal has put together to remove you as a competitor. You can also spot the coworkers who take your stuff, put batteries in your trash, or have sex on your desk when you are not there.
Trust nobody. Nobody trusts 'friends' in the workplace. If they do, they are either naive or they are working a Hustle. They could be working a hustle on you.
Side hustle awareness. Employers tolerate side hustles because they are afraid of the Rotherham effect. Realize that an employer, to get rid of a side hustler, will usually chop a bunch of people at the same time, so the mass firing reflects diversity. If you are seen to be a little too close to the one intended victim, they you could get bundled up with the purged.
Hide your light under a basket. Remember you are dealing with a hierarchy that got those fat pay checks and perks not for being competent, but for being green. They do not like competence, because it makes them look like a racist stereotype. Do the minimum. See how much other people are doing, and do as little as them. You do not want to be a target.
