Can we offer wage hike to head off union campaign?

Q. We are a nonunion company and obviously would like to stay that way. We gave a very modest wage increase six months ago, and we just learned that another company in the same industrial park got hit with a union organizing campaign. I think we should be proactive. Normally we review wages every 12 months, but I want to recommend to my management team that we break that cycle and do a wage increase now. Can we get in any trouble by going ahead with a wage increase now, even though it’s not in keeping with our regular practice? —C.O.
