One of my colleagues seems like she's out to get me. Whenever possible, she does something to make me look bad. How should I respond?

Unfortunately, many professionals will encounter a toxic colleague like this one at some point in their construction careers. If someone's purposely undermining your efforts, you can respond in several ways. One option is to pull the construction executive aside and ask her about her troubling actions. Be matter-of-fact but non-accusatory. Focus on the facts and don't let your emotions get the best of you. If you feel confronting your co-construction executive is futile, document her behavior, collecting concrete evidence supporting your claims and making note of how your performance was adversely affected. Then, bring the matter to your construction manager's attention in an objective, professional manner.
