Yeah been there..done that...but my company pays a minimum four hours OT if I get called back for any reason, and it starts the minute I'm out my door. If they call me back and say "never mind" I still get paid. That being said, I've been doing this long enough that even half asleep, I know which questions to ask, in what order and how often to make a value decision on whether or not to roll on a call. But, it's give and take. If there is ANY doubt whether I should go in.... I go in. That's my call and if I'm wrong, I don't penalize the company for it I'm not that far away and so far my company has always treated me fairly. Our BAS allow me to dial-in from home and evaluate certain systems and areas. Our security personell know they can call me at any time without getting their butts chewed out. In return they work with me on figuring out what's going on and sometimes we both learn something new.I would rather them call me about a fast drip they saw on one of the Reverse Osmossis sytems than extract 500 gallons of water out of a carpet BEFORE I can vacuum, blow and test all the floor circuits.
