I worked HR for 7 years.
-hour lunches, ability to do errands over lunch
-going at my own pace, autonomy, ability to be creative and design my own projects. Really miss this.
-ability to take half days or take a vacation day on short notice
-some flexibility in my schedule
-ability to relax and have fun with coworkers - i.e. parties during work, ability to spend time chatting about the weekend, or going out with them after work. Really miss this too.
-the ability to take things slower/take more downtime if I was not feeling well or burnt out, or, could work ahead.
I don't miss
-mouse on wheel feeling
-feeling like I wasn't making a big enough difference.
