I remember getting reamed by the ops manager for turning back. The flight was one way on min fuel as no holding on the TAF and wx above alt minima. One third of the way out, FS called up with TAF AMD - BKN004 with tempo CBs. I couldn't make anywhere else with fuel that did not have below alt minima.
After much ranting and raving, offloaded some freight, put on appropriate fuel and all was OK (and the wx WAS ****e!). Later provided both TAFs and reasoning to the CP, along with statement that it would have been illegal/reckless etc for me to continue under the circumstances and heard no more from anyone.
Management tasks you to do something. If you can't do it legally or safely, you have to be able to justify why to CP/management. That is part of your responsibility as a line pilot.
