Hard disagree on both needing each other.
Employers can't exist or build their own riches without workers, while workers have existed for thousands of years, much before employers. If we are considering the relationship in adversarial terms, always remember that workers are the only ones actually producing anything of value.
Without workers, garbage won't be collected, water won't be delivered to households, buildings won't be built, and food won't be grown.
The people pushing the paternalistic narrative telling us that we should be "grateful" for the "opportunity" to merely work for a wage have forgotten the French Revolution, the Bolshevik revolution, and all the strikes and revolutions of workers that have advanced our rights to where we have them today. The 5 day work week and the 9-to-5, child labor protections, and workers' rights were not brought to you by the employers. In fact, employers often actively resisted those, and had to be put in their rightful place by their workers.
> It’s nice for wellbeing to be grateful for everything good that happens
Judging by what happened to the employers and the rich during the workers' revolutions, it's probably a good advice for the wellbeing of the work-givers to start practicing daily gratitude towards their own employees. You see, it's just the workers that find themselves more often in the possession of pitchforks and torches.
