I don't know that I'd get upset about a reminder to be sunsmart, but I do try to keep work separate. I don't use work devices for personal things, and I don't use personal devices for work things. I will not put Teams or work email on my personal phone, and I don't share my personal phone number.

After work time I do check for messages at night before bed in case of any last minute meeting requests or anything like that. However, if work expected me to do it, I'd refuse to 😄.

In summary, I don't think work and personal life need to be fully separate, but I think it needs to be at the discretion of the employee not the employer. But even so, I'm not gonna get upset at an email suggesting to wear sunscreen.
