Well, I personally think you made the right choice. Really depends on your bldg, the seniority, but on average, you won't get your summers off until about 20 years in and your kids will be all grown up by then.
Having less than a year in, you will be on the qualified list pretty much throughout your kids years in school. This means you are on call, mostly at night, ending Saturday morning, starting Sunday night....for at least 10 years on average at your seniority level..likely more.
However, if you were even contacted...that's a plus. maybe seniority is low in your bldg but I would go to the feeder office and look at the seniority list then make up your mind the next time around.
When I say summers off, that's pretty much June through the end of August, you won't likely ever get a week off. Think of your time with the kids, time with the family, and every night from around 6 or 7 PM, you will be working until about 7AM for the next 20 years.
There will be times when you cover day runs, but don't count on that all the time.
Check the seniority first, and remember.....as you progress, there will be lists posted and likely others with more seniority will keep entering feeders and you stay on the qualified list.
You will be out to dinner on a Sunday afternoon with the family and get a call asking for you to be at work in 2 hrs. This will happen with only 1 year in for many many years.
Is your wife prepared for this? She will be the one putting the kids to bed for the rest of their childhood.
It's a tough pill to swallow, personally, learn the methods, don't run, don't skip your lunch, and stay in delivery and grow with the kids.
Again, it's all based on seniority, be sure to check it out.
