In my area, gym switching (or the more negative term "hopping") is very common. I'd say most gymnasts over the age of 11 have at least been to 2-3 different area gyms around me. If other parents got their feathers ruffled at families that left gyms, we'd all hate each other by now, and we don't
. Like right now (since its that period of time between the end of season meets and contract re-signing) families literally will say to each other "so, are you staying here for next season or not?" and discussions about our gym versus others and who is looking where are just what everyone talks about this time of year.
Owners, however, will sometimes get upset, but it really depends on the athlete how they will take it. One year a gym that my DD was at was having a mass exodus - like 10+ gymnasts (many from the same group) leaving to go to various other gyms or quitting gymnastics - the owner seemed to react differently to every single one that quit depending on how much she felt they had done for that athlete (or sometimes where they were going). And even then, some of the girls who got the most wrath for leaving then are now back there at that gym! So go figure.
Lol - call me cynical, but if I worked at a gym and someone from another gym called up to tell me how nice a gymnast who was leaving their gym to come to my gym was, I'd almost wonder if the gym was happy to get rid of them
. I'd either think that or if it was a coach that the coach was trying to get a job at my gym. I find it hard to believe that anyone was that nice w/o some self-serving purpose - but that's a general life attitude that I have (I think it comes from watching too much Seinfeld in the 90's). Lol.
