I’m no expert on labor relations and have never been a member of a union (and don’t have strong feelings one way or the other, not that it’s anyone’s business ;-), but it looks to me as if that memo did in fact pass through somebody’s legal department: “… as a supervisor or manager,” “…as an agent of management …” are tip-offs. I also find it interesting that union organization concerns are buried in a memo that spends a lot of space talking about supervisor responsibilities and duties …
On the face of it, though (unless all licensed employees are in fact supervisors or managers, and there seems to be some doubt about that and maybe it doesn’t matter anyhow?) it appears that the memo is “coercive or threatening,” and that it asks employees to spy on union activity. Both no-nos under the NLRA. http://www.dol.gov/olms/regs/compliance/employeerightsposter11x17_final.pdf
And then there is this, from http://www.fklaborlaw.com/articles/Union-salting-Supervisor-dos-and-donts.html
Don’t spy on union activities.
You may not spy on employees to determine their feelings about a union; you may not attend union meetings; and you may not even give the impression that you’re watching employees’ union activities.It’s easy to unintentionally create the impression that employees are under surveillance.
The NLRB has taken a hard line against apparently innocent questions or apparently harmless statements like these: “We know who is involved with the union.” “I hear you’re involved with the union, Betty. Is that true?” “Let me know if you hear of anyone supporting the union; I’d like to talk to them and give them our company’s position.” "They won you over last night, didn’t they?"Even though none of these statements involve a threat or a promise of benefit, the NLRB has held that they imply surveillance of employees’ union activities. The NLRB is not concerned with whether the statement is true, or whether the supervisor intended any unlawful effect, or whether there was actual surveillance. They have found that such statements have a “reasonable tendency” to discourage employees in exercising their rights, since they create the impression that the supervisor has sources of information about union activity.Here are general rules for your supervisors to follow:
You may not imply that you have someone on the inside telling you about union meetings or insinuate that you know when and where union meetings have been held (unless the notices of meetings are public knowledge). Do not create the impression that you know exactly what has been said at these union meetings.
You may continue to visit local bars, pubs, restaurants and other establishments, even if a union meeting is taking place there, as long as you have had a frequent practice of attending these places. Before going to any establishment where you know a union meeting is to take place, be sure to check with company officials first. They will give you legal clearance on whether or not to go ahead with the visit.
You may not request employees to report the identity of pro-union sympathizers to you or to other officials of management. Also, you may not encourage those you supervise to engage in surveillance of the union activities of their co-workers, or to reveal who is for or against the union. Do not question (even when you are off company premises) an employee’s spouse, relative, neighbor, friend, or co-worker as to whether the employee is for or against the union.
You may not tell employees that co-workers are informing you about union activities, or that some employees are “keeping you posted” on what is going on with the union; do not imply, even in a joking way, that you are receiving information about union activities in the plant. Do not even start a conversation with the statement, “I’ve heard that some people are interested in the union…” All these statements can be viewed by the NLRB as creating the impression of surveillance.
