In May, 2020 3M HR published a document titled "Vacation Policy FAQs". One of the FAQs is as follows:
Q: I reach my ten-year service anniversary with 3M in August. When will I get my extra week of vacation?
A: Your Annual Vacation Hours included your extra week of vacation at the beginning of the year, so it is available for use beginning in January of your anniversary year.
