Worker could mean IC only, or IC and managers.

Managers could include owners or not.

A worker is worth the least the employer thinks they'll stay for. I've heard one too many new, smart-ass line manager say "oh, I got her/him cheap".

To advocate for oneself as a worker, it requires continuous calibration, documentation of results, and well-timed initiative to expand within degrees of freedom that would be desirable to maximize bottom-line results directly or indirectly.

Boundaries. Those aren't the problems of a worker. It's best to be an excellent worker if one is going to be a worker, but that's still not enough. It also requires communication: advocacy, persuasion, and showcasing results to get the job, keep the job, and then to periodically justify and negotiate more income above the rate of inflation. Below the rate of inflation is a pay cut.

Be exceptionally useful, helpful, and professional.. just don't help managers find ways to pay you less or work yourself out of a job unless you already have a thriving side-hustle. ;) 996 and crash schedules are for the birds.
