Loparex LLC owns and operates a small manufacturing plant in Hammond, Wisconsin. When a handful of the 200 employees working at the plant began to drum up interest in unionizing the workforce, Loparex pushed back by placing a number of restrictions on organizing activity at the workplace. Loparex’s actions were soon brought to the attention of the National *544 Labor Relations Board, which concluded that Loparex had engaged in a number of unfair labor practices in violation of the National Labor Relations Act, § 8(a)(1), 29 U.S.C. § 158(a)(1) (“the Act,” or “the NLRA”). The Board ordered Loparex to cease and desist and to take several affirmative steps to remedy its past violations. Guided by the deferential standard of review applicable to the Board’s decisions, we conclude that its order should be enforced.

Loparex owns multiple production facilities scattered across the country; at these plants, it manufactures polycoated and silicone-coated papers and films. In June 2006, Loparex acquired the Hammond plant from the Dоuglas-Hanson Company. Though the employees in that location had attempted to form a union when the plant was under the ownership of Douglas-Hanson, these efforts had died off by the time Loparex took over. With Loparex at the helm, employees’ prounion sentiment lay dormant until early 2007, when the company announced several controversial employment policies. Spurred in part by their disagreement with the company’s recent actions, a small group of employees renewed their efforts to unionize thе plant. This campaign was not warmly received by Loparex officials.
In the back-and-forth that followed, Loparex imposed several limitations on union organizing at work. After union supporters posted material on company bulletin boards in March 2007, Loparex issued a policy statement that required employees to obtain approval before placing any material on the boards. A few months later, several employees attempted to distribute prounion flyers in Loparex’s parking lot, but they were stopped by company officials. Around the same time, employees passed out union buttons in the plant and left some of them near a time clock for other employees to pick up. When company officials learned of this activity, they quickly called a meeting and told the union advocates that they had violated company policy. Management also discouraged employees from talking about the union during working hours. Then, in June or July 2007, Loparex informed all of the shift leaders working at the Hammond plant that they qualified as supervisors under the NLRA and were thus prohibited from participating in union activities.
Following these events, Teamsters Local 662 filed three separate unfair labor practice charges. After a hearing in May 2008, Administrative Law Judge (“ALJ”) Paul Bogas issued a decision in November 2008 finding that Loparex had violated the Act in several ways: by promulgating its bulletin board policy because of antiunion animus; by announcing unlawfully broad constraints on employee communications relating to unionization; and by treating shift leaders as though they were supervisors under the Act. Loрarex filed exceptions to all but one of the ALJ’s findings. (The ALJ also found that Production Manager Todd Dennison violated section 8(a)(1) of the Act in June 2007 when he informed a group of employees that they were prohibited from speaking about union organizing at work. Since Loparex did not contest this conclusion before the Board, we summarily enforce the ALJ’s order on this issue. See
NLRB v. Alwin Mfg. Co.,

Our review of the Board’s decision is deferential. We accept its factual findings if they are supported by substantial evidence, and its legal conclusions “unless they are irrational or inconsistent with the [Act].”
Ryder Truck Rental v. NLRB,
A. Loparex’s Bulletin Board Policy
The Board adopted the ALJ’s conclusion that Loparex violated section 8(a)(1) when, against a backdrop of a corporate policy that permitted employees to use the bulletin boards for a variety of non-work purposes, it shut off access in response to union organizing activity. As support for his finding that the purpose of the new policy was to inhibit the organization campaign, the ALJ pointed to a confrontational meeting between management and a union supporter that took place a few months before Loparex issued the policy. The evidence оf an upsurge in prounion activity following that meeting, in the ALJ’s view, supported an inference of Loparex’s knowledge and distaste for the employees’ organizing efforts. This aversion played a key role in the formulation of the bulletin board policy. Loparex objects that there is only a weak temporal connection between the earlier confrontation and the eventual issuance of the new bulletin board policy. Loparex adds that the evidence does not establish that the company was even aware that prounion materials had been posted on company bulletin boards.
Section 8(a)(1) offers employees broad protection from employers’ attempts “to interfere with, restrain, or coerce employees in the exercise” of their statutory rights to organize under section 7. 29 U.S.C. § 158(a)(1); 29 U.S.C. § 157. Yet this statutory entitlement does not give employees an unfettered right to use a company’s bulletin boards to stir up interest in unionization. See
Fleming Companies, Inc. v. NLRB,
*546
If an employer is alleged to have acted with an antiunion purpose, we apply the analytical framework set forth by the Board in
Wright Line, a Division of Wright Line, Inc.,
In determining whether an employer acted improperly, the Board is entitled to rely upon circumstantial evidence. See
SCA Tissue North America LLC v. NLRB,
Beginning in early February 2007, pro-union activity at the Hammond plant slowly began to increase. Schillinger started to wear union buttons and hats to work, and he donned a union t-shirt for about half of his workdays. On March 9, 2007, a group of employees posted a prounion flyer on one of Loparex’s many company bulletin boards. The flyer was taken down shortly after it was posted; thereafter, it was repeatedly reposted and taken down. The record does not reveal when these postings and re-postings took place, or how many times the flyer was replaced, and so we cannоt tell whether the flyer was displayed on the company bulletin board after March 9.
These events support the Board’s conclusion that Loparex was motivated by antiunion animus when it enacted its bulletin board policy. Schillinger’s discussion of unions with Loparex’s management and his prounion apparel put the company on notice that union organizing efforts at the plant had (re)commenced. Loparex points out that there is no evidence indicating that the company knew that union activists had placed a flyer on one of the many bulletin boards in the plant. Nonetheless, the Board was aware that this was a relatively small plant. In addition, it was entitled to rely on the suspicious timing of the
*547
policy announcement, immediately after a three- or four-month period in which Loparex witnessed an uptick in employees’ organizing efforts.
Cf. Brandeis Machinery & Supply Co. v. NLRB,
The inference of an antiunion purpose is reinforced by the hostility Loparex’s management displayed toward Schillinger at the February 2007 meeting. The Board, affirming the ALJ, reasonably viewed the circumstances leading to the meeting as suspect. Presumably, Risler had already tipped off management about Sehillinger’s opposition to the new policies and thus there was little reason to interrogate Schillinger about his conversation with Risler. The management officials who called the meeting had worked at Douglas-Hanson when Schillinger was fired for his union activity. By warning Schillinger at the end of the meeting not to speak about the union, Koats came dangerously close to illegally prohibiting an employee from engaging in prounion solicitation during the workday. See
NLRB v. Aluminum Casting & Engineering Co.,
B. Distribution of Union Literature in the Parking Lot
In May or early June 2007, Schillinger, Chris Meeker and two other employees handed out literature to coworkers in the company parking lot and placed union literature on car windshields. Shortly after they got started, three Loparex officials came out to the parking lоt and informed them that they were violating company policy. The Board endorsed the ALJ’s conclusion that Loparex’s restriction on union organizing in the company parking lot constituted an unfair labor practice under section 8(a)(1).
In protecting employees’ right to organize, section 8(a)(1) of the Act recognizes that employees’ organizing activities may substantially interfere with employers’ property rights. See
St. Margaret Mercy Healthcare Centers v. NLRB,
An employer may not, however, prohibit all solicitation in a company parking lot. Loparex contends that this is not what it was doing; instead, it argues, it only banned the practice of placing flyers on car windshields. The Board saw matters differently; it agreed with the ALJ’s finding that the Loparex officials were telling the employees that they could not distribute any union matеrials in the parking lot even if they were off-duty. Because the record provides some support for both positions, this was a classic call for the Board.
Cf. NLRB v. Aluminum Casting & Engineering Co.,
*548
We add that even if Loparex had proscribed only distribution on car windshields, the Board still could have found that its policy violated section 8(a)(1).
NLRB v. Village IX, Inc.,
C. Distribution of Union Buttons in the Lunch Room
In June 2007, Meeker left a pile of prounion buttons lying on a table next to a time clock. On June 20, Todd Dennison and Lisa Koats, both members of Loparex’s management team, held a meeting with Meeker, Schillinger, and another employee about their distribution of the buttons. Dennison warned, “I don’t want to catch you passing [buttons] out, Okay, I don’t want to see them laying around.... You can pass them out when you’re outside, on your own time, but when you’re here working, you, you, need to be working.” The ALJ concluded, and the Board agreed, that the prohibition was overbroad because employees could have believed they were barred from soliciting near the time clock, a non-wоrk area, during nonworking hours.
Loparex comes close to conceding that such an expansive rule against solicitation on company property would violate section 8(a)(1). Our review satisfies us that the Board’s position finds support in the evidence. See
Aluminum Casting,
Loparex’s argument on this point is terse and largely unsupported by pertinent authority, and so we were concerned that it might be forfeited. See
White Eagle Coop. Ass’n v. Conner,
*549
Nevertheless, this is of no help to Loparex. The Board affirmed the ALJ’s finding that the no-distribution rule was overly broad, because Dennison and Koats did not state that they were disallowing distribution only in work areas of the facility. By purporting to restrict distribution in non-work areas, during break times, they stepped over the line. In so finding, the Board was following long-established policy to the effect that “a rule is presumptively invalid if it prohibits distribution on the employees’ own time.” See
Our Way, Inc.,
D. Shift Leaders as Supervisors under the Act
In June or July 2007, Loparex announced to the shift leaders working at the Hammond plant that they were “supervisors” within the meaning of the Act and thus prohibited from engaging in union activities. See
NLRB v. Kentucky River Community Care, Inc.,
The term ‘supervisor’ means any individual having authority, in the interest of the employer, to hire, transfеr, suspend, lay off, recall, promote, discharge, assign, reward, or discipline other employees, or responsibly to direct them, or to adjust their grievances, or effectively to recommend such action, if in connection with the foregoing the exercise of such authority is not of a merely routine or clerical nature, but requires the use of independent judgment.
29 U.S.C. § 152(11). To prove that employees qualify as statutory supervisors, an employer has the burden to prove: “(1) [the employees] hold the authority to engage in any 1 of the 12 listed supervisory functions, (2) their ‘exercise of such authority is not of a merely routine or clerical nature, but requires the use of independent judgment,’ and (3) their authority is held ‘in the interest of the employer.’ ”
Kentucky River,
Before we address each of these contentions, it is helpful to provide a general description of the role shift leaders play at the Hammond plant. Each shift leader is part of a small crew typically comprised of five or so workers. Shift leaders work directly under a team manager, who is generally assigned to the same 12-hour shift. While shift leaders, like other crew members, operate the production machinery, they also help out other crew members, answer questions, and provide needed supplies. In addition, shift leaders are required to assign crew members to various machines in order to accomplish the tasks allocated to the crew in the daily job priority sheet.
1. Authority responsibly to direct
To establish that an employee has the authority responsibly to direct another co-worker, the employee must be accountable for the co-worker’s performance. See
NLRB v. Adam & Eve Cosmetics, Inc.,
Loparex argues that
Oakwood Healthcare
was wrongly decided because the Board inappropriately read into the statute an additional requirement that the employee must have the capacity to take corrective actions. The Board asserts that Loparex has forfeited any argument directly challenging the case. See 29 U.S.C. § 160(e). While Loparex argued to the Board that its shift leaders did direct their co-workers, it neither attacked
Oakwood Healthcare
nor raised the issue of corrective action. This may well amount to a forfeiture of Loparеx’s argument on appeal. See
Masiongale Electrical-Mechanical, Inc. v. NLRB,
The Board’s position, in Loparex’s opinion, is nonsensical, because the ability to discipline is a statutorily recognized supervisory power. Assuming that “corrective action” is not different from disciplinary action, Loparex argues that the Oakwood Healthcare rule effectively eliminates “responsible direction” as a separate basis for establishing an employee’s supervisory status. Loparex contends that the Board applied the “corrective action” requirement in a manner that conflated the idea of discipline and responsible direction.
The most we can say is that the reference to responsible direction in section 2(11) of the Act may be ambiguous. We thus owe
Chevron
deference to the Board’s decision in
Oakwood Healthcare.
See
Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
At the same time, in applying the “corrective action” requirement, the Board must be careful to distinguish between corrective and disciplinary action in order to ensure that each part of section 2(11) has meaning. Yet, despite Loparex’s claims to the contrary, there is little indication that it equated these two forms of supervisory power. Instead, the Board accepted the ALJ’s finding that shift leaders lacked authority to take corrective action because they were unable to control their crew members in any meaningful sense. The ALJ pointed out, for example, that if a member of a shift leader’s crew is insubordinate, the shift leader’s only option is to submit a factual report detailing the issue to her team manager for consideration. The ALJ found that this meager reporting power could not be construed as a form of corrective action.
Since Loparex did not provide any other evidence indicating that shift leaders had authority to control crew members, the Board did not need to illustrate the difference between corrective and disciplinary action. We add that we have no trouble imagining separate domains for these two kinds of action. For instance, an employee might be said to take corrective action if *551 she requires a coworker to stay late to complete a project that has fallen behind schedule. Placing this small burden on the employee, however, would not amount to a disciplinary action that could affect the employee’s job status.
We are satisfied that substantial evidence supports the Board’s determination that shift leaders do not possess the ability to take corrective action. This court owes deference to the Board when it is engaged in the difficult task of distinguishing between “true supervisors” and other employees undеr section 2(11). See
GranCare,
2. Authority to assign
While the Board assumed that shift leaders had the authority to assign work to crew members, it also concluded that shift leaders did not exercise independent judgment while assigning the work. See
Kentucky River,
Loparex contends that the Board should not have ignored Monicken’s testimony. Yet Loparex is unable to point to any evidence that any other shift leaders adopted Monicken’s practice of assigning work based upon workers’ relative productivity. In fact, the ALJ specifically found that Monicken’s job as shift leader differed in many respects from other shift leaders. Since Loparex had the burden to demonstrate independent judgment, we conclude that substantial evidence supports the Board’s decision to focus on Meeker’s approach to work assignments.
Retreating to Meeker’s testimony, Loparex contends that it is irrelevant that Meeker failed to exercise independent judgment. As long as Meeker was empowered to make independent judgments about work assignments, Loparex asserts that he qualifies as a supervisor under section 2(11).
Cf. Dreyer’s Grand Ice Cream, Inc. v. NLRB,
We conclude that the Board’s order should be Enforced in its entirety.
