Ex Employer Is Seeking Legal Action Over A Non Compete Clause

Hey everyone just looking for advice.

I am a strength and conditioning coach and i recently took a new job 10 miles away from my old one.

I told my old boss and he said he was going to contact his lawyer because it a violation of our non compete clause. The clause says I can’t work for anyone in a 20 mile radius for up to a year after I leave.

I’m a low wage employee that was only making $15 an hour and I can’t really afford a lawyer. The job I got was a dream position for me and I’m really depressed knowing it could be taken away from me.

What should my next steps be, my new boss doesn’t seem concerned but I received an email from his lawyer today.

And I just don’t know what to do

(Also a couple more things. I live in Pennsylvania and I’m not familiar with how they rule against these cases. And technically my old facility was a baseball training facility where I did private baseball lessons along side lifting classes, my new facility is purely strength and conditioning if that makes a difference )

Any advice is appreciated
