One more thing. Stop using your cell phones to call dispatch and SAM when on the plane. Use ARINC, It was set up specifically for that reason. Less convenient of course but let the company pay for those minutes.

When you are on your 3:59 sit keep in mind you are not on Field Standby. Before you answer your cell phone when the crew desk calls check your schedule from your smartphone to see if the reassignment is in your best interest.
