One thing I ALWAYS remembered were the days our office was "officially" closed. When I started working for the firm, and for a couple of decades afterwards, we had a lot of days off, EXCEPT the Friday after Thanksgiving. Then they decided to take away certain holidays, and in exchange gave us the Friday after Thanksgiving.
~Huh?~
Since we were officially open 24/7, our only "official" holidays were Easter Sunday, Thanksgiving Day, Christmas Day, and New Year's Day. Years ago we used to get Election Day off, but then they decided, since the polls were open until 9:00pm, we didn't need the whole day off, especially in a non-Presidential election year.
~Grrrr~
The only good thing about getting the Friday after Thanksgiving off was, I could save 3 vacation days, and take the whole week off. Once I stopped taking my whole vacation at once during the years I was traveling, I started taking the first 2 weeks of July, and the last 2 weeks of December as my vacation, which usually afforded me at least 2 of the days I needed for Thanksgiving week (July 4th and Christmas Day), so I wound up with 5 weeks vacation each year, instead of the 4 weeks we were allotted. That WAS a good thing.
