Everything in life is a trade-off. Being an employee at a decently sized company is about trading certain pleasantries (e.g. having to deal with the 9 to 5 drill) for certain benefits (e.g. a stable income).

Similarly in jobs that have no paid overtime, you are usually compensated a bit more and don't always have to work overtime.

Taken care of in this context is talking about the stability a company provides you. It isn't given to you out of charity, you certainly earn it, but it doesn't come free either.
