I'll have to see if I can find it, but I believe that's correct.
In MA, this makes a difference: Did you travel during regular working hours, or did you travel during off hours? IT MAKES A DIFFERENCE if you are due any travel time or not.
In 48 out of 50 states, there would be NO laws that would compel them to pay you one cent. You happen to be in one of the two states that does have at least SOME requirements for pay, but if I remember correctly they are ONLY required to reimburse you for travel that occurs during regular business hours. If you traveled after hours, then there is NO M.G.L. section that will compel them to pay you anything.
Nor the hotel, meals, other expenses, cbg?
Not the way I remember it. Only mileage, and only mileage incurred during business hours. But I'm still looking for the reference - I may need to check with Phil Gordon.
I got my answer. Thanks to everyone.
