I believe it has been noted on this board before that according to the current union contract, management has the option of getting rid of two on-air employees a year if they so desire. Perhaps that's the reason for Varnum's departure.
What is interesting to note is it's now Channel 10, and not 8 that seems to be using the "revolving door policy" when it comes to personnel.
Since I don't watch 10, I really can't comment on Varnum's work, but I do wish her the best of luck in finding another job.
