Unless you'd like to join former Jet Blue flight attendant Steven Slater in the unemployment line, you've gotta watch you say at work. Next time a co-worker tries to get you to help save him/her ass on something he/she should've done yesterday, say, "I'm happy to help if I can — I'll get to it after I do such-and-such?" Basically, you're managing opposition by giving him/her nothing to oppose. Nice, huh?
