EVERY Airline you work for will want you taking company planned fuel. As far as i’m aware none I have worked for have disciplined anyone over taking extra. Most fuel policies will give the PIC scope for discretionary uplift and they know ultimately it’s up to you.
If your workplace is actively enforcing landing with fuel caution lights on (LOL) then I suggest you find a better place to work.
Lets face it, nobody enjoys checkrides but It shouldn’t force a crew to put on a fuel load that makes them uncomfortable. If it’s true sounds like massively ****house operation anyway.
