I just recently quit my long term employer of over a decade. I had two weeks of pre booked vacation time in the calendar, so I gave them 4 weeks of notice and worked a week, took week off, repeated. During this 4 week period, I trained 3 new employees at their asking and thought I was leaving on great terms. For my final paycheck they deducted 6.5days of "unaccrued" vacation and short paid me by few thousand dollars. Are they in the right, or do I have an issue worth fighting for?
