I've worked many different shifts through the years, while climbing the seniority ladder - but recently I moved to a set schedule, every Wednesday, Saturday and every third Sunday. In theory, I thought it would be a good shift, but management decided to change us back to the standard Kelly (1 on, 1 off, 1 on, 1 off, 1 on, 4 off) and I realized how much I had missed the rotating shift. People do not like to trade for my Saturday shift, and I was always missing out on events with my "non-EMS" friends and family. So, can't wait to go back to a rotating schedule and get a few weekends off here and there.
On the other hand, my husband - also a medic - works four (4) 12 hour shifts a week, great for the overtime built in, but kills any time we would have had together. Fortunately, he will be moving to a 48/96 schedule soon - then maybe we can have some time together again.
In the end, 10 days a month - even when we are up the entire 24 running calls, DEFINITELY beats working 4 or 5 days a week - I absolutely value my time off and have been able to actually attend my kids ball games and concerts, go back to school myself, and I'm home with the kids 20 days a month - what more could I ask for.
