In the US market, where union participation is also very low, it's weird to me that this is an important reason people stay in their jobs, may influence what kind of jobs you take (full time vs contracting?), but: - job offers generally do not want to get into details on the health insurance offering. it's not a main "competition" point - except when subject to some kind of union negotiated contract, the employer can…
And in the US a new worker can only join the healthcare plan during certain times of year! New workers often have to wait months with a health insurance gap before they can get on the new plan.
However, you sometimes have to wait for the plan to begin coverage. Something like "after 30 days of employment", or "on the first day of the first full month of employment". These are indeed idiotic limitations.
Worst case scenario, if you are changing job and something really bad happens during these 2 weeks where you don't have coverage you can retroactively enroll in COBRA.
