I made this mistake last year, choosing a start date of the 1st. Normally, this would not have been an issue, but it took my employer several weeks to have their benefit management company activate my benefits. Fortunately, my act of loudly demanding they make the benefits retroactive to the 1st got things sorted very quickly. But, this is because I knew how things worked. I would also recommend to US-persons to not switch jobs around a month boundary. The employer-linked healthcare system is burdensome to both employers and employees. It’s not going to change without a dramatic change to the group insurance model.
