Aircraft
I was the Second in Command (SIC) and Pilot Monitoring (PM). Upon climbout; we received a yellow caution message 'PRI STAB TRIM FAIL;' indicating a failure of the primary stabilizer trim system. I reviewed the QRH; selected secondary trim; and the aircraft then handled normally. The QRH directed us to keep the speed under 250 KIAS or .75 mach. I contacted the Assistant Chief Pilot for guidance. Did he wish us to continue to another airport where a recovery could happen; or did he want us to return. There was no instruction in the QRH to 'Land as soon as practical or possible' so I felt that left the option open to go somewhere else. The Assistant Chief Pilot I spoke to was very specific that he wanted the aircraft on the ground. I informed him that we were >3k lbs over landing weight; and he reiterated to land. Given that there were thunderstorms in the vicinity of ZZZ; and that it would take at least 45 min to burn off enough fuel to get under landing weight; we decided to perform an overweight landing. I notified ATC; and requested that CFR be waiting for us on landing. A normal landing occurred; the aircraft was not damaged and the flight was eventually cancelled due to lack of recovery aircraft. The crew acted in the best interest of the passengers and the company by landing ASAP.
