My move to Chicago was in October 2010. October is about as close to competition season as you can get without actually being in it. But I was offered a great job here that paid about 30% more than I was making and my sister lives here. The opportunity was just too good to pass up. I felt awful when I had to tell my girls' gym that we were leaving at such a bad time in the season. I literally burst into tears while I was telling them. :oops: And I was so upset about letting their teams down.
You want to know the gym owner's reaction? She smiled HUGE and said that it was so awesome that I found such a great opportunity that would help my family so much. She said my daughters could continue to come to practices until we left to keep their skills so when we moved they'd be ready for a new gym. She let us participate in the parade that had been scheduled. She found buyers for both the uniforms I had to sell - and got me a great price (full price for the uniform since it was brand new still with tags, and I threw in the bows and practice wear, so I got almost all my money back).
What I'm getting at is that gym owners and coaches are human, with hearts. If presented with as much notice as is possible, an obvious reason that clearly must take precedence over cheer (yes, even gym owners realize that these reasons exist), and you make it clear that you genuinely are unhappy that you have to leave the gym, they will probably surprise you with their support. (If they don't and they have a fit, then whatever. Leave and don't give it a second thought. If they can't bounce back in AUGUST from losing a couple kids then this might not be the business for them)
Very long, wordy way of saying TAKE THE JOB. Good luck and congrats on the job offer!:chestbump:
