Ron,
I realize I only get one side of the story but from the side I get, it certainly sounds like JT doesn't treat their employees well. I got to know the first employee over there pretty well and I know the other two very well. In addition their view point on how they are treated (even if it is wrong, which maybe it is) does effect your customers as happier employees will do a better job. Nobody likes going into a store and being helped by a pissed off employee. Trying to blame your employee's for poor sales when you no longer carry quality products is just wrong.
In addition, I have emailed you before with comments/feedback and I never heard back. I don't know if you just didn't read the email, didn't care, or just didn't feel like it needed a response.
As for good business practice... In my experience except in fields such as information security, they usually give you a week. The last job I worked at, they gave you two. It was up to you if you actually came in or not, but they gave you two weeks pay.
Ron, even with employee relations aside (and there will always be two viewpoints on that) it seems that JT is being run into the ground. Once again, I know that most business decisions go above you but what happened to the days where JT actual sold stuff we want? The only reason I have gone into JT in the past year and a half was for repairs, some SRC parts for an emergency repair, or as a meeting place for something else. The fact that JT is having to close so many stores shows something is wrong, but the people with the money there either can't figure it out or don't care.
