There are two general schedule types, a “42-hour” and a “56-hour.” Firefighters usually work a rotating schedule, mostly on an 8 week cycle (although I’ve heard of others, eight is by and far the most popular). The 42 and 56 are the average number of hours worked per week when examined over the 8-week rotation.
The reason there are 42’s and 56’s come from the number of hours in a week - 168. If you have four groups/shifts working, you work 42’s (168/4 = 42). If you have three groups/shifts working, you work 56’s (168/3 = 56). There are some variations when it comes to paying individual firefighters for hours worked, but that’s how the shifts are derived.
My shifts are 1-1-1-5; one 24 hour shift, 24 hours off, a 24 hour shift, 5 days off. I work from 7am until 7am the following day. That is the most common one I’ve seen in the northeastern US, almost all of the northeast work 42 hour shifts, 56’s are rare. There are some variations of the 42, such as 1 on, 2 off, 1 on, 4 off or 1 on, 3 off. This week I work Wednesday and Friday. Next week I work Thursday and Saturday. The following week I work Friday and Sunday, repeat ad nauseam.
About half of the departments that work the 42’s do 24 hour shifts, the others do what are referred to as 10’s and 14’s: two 10-hour days, two 14 hour nights, four days off (or a variation of). My department (an oddball) worked 8’s and 16’s until 2001, when we changed to 24’s. I’ve never heard of anyone else with 8’s and 16’s.
Departments that work 56’s are usually 1 on, 2 off. I have heard of departments moving to 2 on, 4 off; but I don’t know how common that is becoming.
There are also departments (usually military) that work 84 hour shifts, one day on, one day off. I don’t know how their overtime situation works, as FLSA only requires overtime in excess of 56 hours (averaged) per week. Firefighters get their own special section of FLSA, as Congress recognized our wacky work arrangements. State laws and collective bargaining agreements may spell out different overtime rules. In my department, we receive overtime for any hours worked outside of your normal shift hours. I don’t know how others do it.
As for what goes on during a “typical” day? Come in before 7am. Get the previous day’s news and happenings from the off-going shift (what happened yesterday, latest gossip, status of the apparatus and building, construction or closures, new memos, union news, etc). Finish coffee while we all watch the morning news. Around 8, start checking the trucks. Radio test at 8:30. House duties until they’re done. Training of some sort around 10 until just before noon. Lunch. More training in the afternoon, or time to tend to your own projects/assignments (inspections). Chiefs go home between 5 and 5:30. Supper around 6-7 or so. A little tv after supper, and we can head to bed after 9:30. Up by 6am, shift change at 7am.
Oh, and if there are any incidents during anything that happens in the above list, you stop what you are doing and respond. We average three to five calls per day. Not busy by any stretch, but its enough.
Managers and bean counters want 24 hours of “work” to be completed during a shift. Unfortunately, it doesn’t work like that. I can’t, in good conscience, beat my guys up for 22 hours and hope I don’t have an incident in the 23rd hour. I need my guys in good condition, which means allowing them to rest (and get paid). There is a story in my department, dating back to the early 1980s, of our state’s administration ordering the firefighters to take an unpaid lunch from 12 to 12:30. An incident occurred two days later, and the fire department didn’t respond - they were on their unpaid lunch break and not “at work.” That afternoon, the order was rescinded. Old fashioned Taylor/Ford/Weber ideas of “work” do not jive with the fire service. In our modern world, the newfound dislike of public employees has put us squarely in the crosshairs of up-and-coming political actors who want to reform the “lazy firemen.” Yes, it can be a very easy job sometimes. It can also be an excruciatingly difficult job at other times, it all averages out in the end.
At least we’re not working the 15 days on, 1 day off schedule that was popular until the end of World War 1.
Regarding firefighters and side jobs. On average, it takes someone 7 years to become a career firefighter, between the certifications needed to apply, the testing process, and waiting for an opening. In those seven years, that person needs to feed themselves somehow, so most take up a trade of some type. I was a machinist before I was a firefighter. We have plumbers, electricians, carpenters, mechanics, commercial drivers, etc, etc, who become firefighters. We work most of hour hours all at once, leaving us with time off. If you have a properly staffed fire department, there shouldn’t be any overtime. So we give you a job where you (should) have no prospect of additional income, but you are trained with a usable and potentially valuable skill. Thus, we have side jobs to fill the hours. It’s when the side job takes preference over your firefighting job that problems arise.
