There’s a grim, apologetic vibe to these messages — I’m sorry I’m taking time for myself but I’ll try to check in on occasion!

It would be best if you were to provide these important notifications at least two weeks before the holiday shutdown. Employees should also be reminded regularly that the company will not be open during those important days.
