Stop in for a cup of coffee

Our monthly retirement pay was based on your highest three out of five years pay.
I'd been gone five years with the military then so came back to fix my retirement.
My last two years I ran an evening shift Detective unit. I stayed for every late call and worked Detective call back every six weeks for two weeks at a time.
With all that I was working 20-40 yours of overtime a pay period.
With all the OT plus comp time, sick and vacation leave included I got a $1200 a month raise when I retired.
After I left, they changed the rules and Sergeants were no longer allowed to work call back.
