I look forward to me and my friends setting a date for our cancelled Italy trip. That was a killer to have cancelled but also understandable.
Work for me still involves a lot of in person travel to plants, so that'll never change (and didn't too much over this pandemic besides being more of a PITA). The biggest improvement I hope is we get to a place where we can get more of my fellow coworkers back into the travel rotation (a combo of layoffs back in June, and then several of the ones we still have having either very young kids/immune compromised themselves or their spouses) meant the burden of "being there" fell on a very very small group, and did that get old quick. It is understandable, and you grit through it, but still, it wears on you.
I do enjoy that it does seem like increased flexibility with being at home is here to stay though. I just hope this next year we get more people back because somehow we're going to be busier. I ended up forfeiting (sure compensated but still) 7.5 PTO days this year because I couldn't take them with all the travel and dashing everywhere. I need that to stop. That's nearly 1/2 of my days off just poof, gone.
