"It has been an incredibly tough couple of months for our entire family," the Princess of Wales said in a video filmed in secret and released Friday.

The state was on the cusp of making new rules to protect people who work in places like warehouses from dangerous heat. A last-minute shake-up leaves workers wondering if they'll be safe come summer.
