False accusation is probably hard even for saints to bear. In most cases I would defend myself vigorously and offer any proof I had.
At work it can be a different story because of all the politics involved and because you must sustain working relationships with people you never actually chose as associates and possibly do not love.
One time that it happened to me at work, I learned two important things: (1) one of my colleagues was (is) a slacker and a liar; (2) there were times when my boss wasn’t going to stand up for me, even though she believed me and also the fourteen separate pieces of evidence that I supplied. CYA measures certainly did not suffice in that instance. I let it go but didn’t forget it.
I also didn’t know what kind of politics there were between her and V—, the other person’s manager, other than that V— was favored by their boss, and my manager, S—, wasn’t.
The second instance was a sharp difference that occurred between me and a different co-worker, in which I had done a requested markup (a heavy one) of a document and she got angry and declared that she didn’t have time to make all those changes. We exchanged some words. She then took the document and threw it across her cubicle, and I left. I immediately wrote a detailed account of the incident, as honest and objective as I was able to make it., including the exchange of words, and sent it to S—.
The co-worker, meanwhile, went straight to her manager and accused me of flinging the document across her cube. Wouldn’t you know, her manager also was V—.
S— and V— met. Neither would yield ground even though the colleague in question was known for her temper tantrums and irrational and accusing behavior (everyone could hear it, and everyone had been scathed by her at one time or another) and had been put on notice many times for it, and I was consistently praised for my professionalism and my ability to communicate well with anyone.
In the end S— came back and told me it was a stalemate because V— believed the word of my co-worker and would not hear otherwise. I already knew that S— was not going to go all the way out on a limb for me, even though she was normally a strong advocate. Now I learned (1) that reputation does not count for as much as I thought it did and (2) that V— probably had a very different view of me from S—‘s. I let it go and didn’t forget it.
Then one day S— was laid off without warning. V— is now my manager.
I keep my head down and try not to cause her any trouble, biding my time.
The third time, very recent, was a small but significant incident. Two members of my functional group were having a problem with an offshore team member. We agreed to inform her local mentor. Since I am usually the spokesperson for this group, I agreed to approach the mentor. She reacted very defensively and accused me (in a message copied to my group) of making baseless assumptions and jumping to conclusions. I gave my group members two deliberate opportunities to come forward with their proof that these were not baseless assumptions, but they remained silent. So I wrote privately to the mentor and told her that I was speaking on behalf of my group and that my group members had explicit evidence of their complaints.
Now I simply remember that two of my closest group members were willing to let me twist in the wind rather than speak up when challenged. From this I learned (1) not to trust them too far and (2) to avoid speaking on behalf of any group again in this present climate of risk, suspicion, and mistrust. Everyone is worried about their jobs, and no one is willing to be exposed.
In each case I came off poorly, but I learned something. I do not think I would have been better off with a major confrontation. The lessons were valuable. Time will tell if I gained points for putting the team ahead of personal vindication or if those are all now black marks on my record that will make the next accusation easier to believe.
