In the aftermath of this summer’s Janus v. AFSCME Supreme Court decision attacking public-sector unions, the University of Illinois at Chicago is rapidly becoming a bellwether for how those unions might sink or swim in a world without fair share.

UIC prides itself on being one of the most diverse college campuses in the country and one of the most welcoming to working-class students. The city’s only public research university and home to a vast hospital system, UIC employs a cross section of public-sector workers including nurses, teachers, clerical workers, and maintenance workers, nearly all of whom are unionized.

In recent years, university officials have rightly issued public statements critical of government actions that harm members of the campus community, including Trump’s Muslim ban, the Illinois state budget impasse, and the House GOP’s failed attempt to tax graduate student tuition waivers. But since the Supreme Court issued its anti-union decision in the Janus case this June—threatening the collective bargaining rights of thousands of university employees—the administration has been silent. Instead, through their actions, administrators have indicated a willingness to use Janus to engage in union busting.

In the first month after the ruling came down, the university payroll office failed to deduct dues from hundreds of card-signed union members from several unions on campus, including UIC United Faculty (UICUF), the Illinois Nurses Association (INA), SEIU Local 73, and my own union, the UIC Graduate Employees Organization (GEO). In the case of GEO, this cost our relatively small local of graduate student workers a whopping $10,000.

UIC’s failure to deduct member dues in July was not only illegal, but it also effectively silenced workers who actually want to pay dues because they enjoy having workplace rights. The administration openly admitted they hadn’t deducted dues, but said they weren’t going to do anything to remedy this obvious legal violation. Instead, they’ve forced the unions into a protracted grievance and arbitration dispute, apparently hoping they can simply tire us out or outspend us in legal fees.

Further, the administration is claiming the right to unilaterally process membership revocations without notifying the unions, which goes against university HR’s own policy. They also refuse to provide us with timely information about which employees are in our respective bargaining units, which is especially harmful for GEO since our bargaining unit changes dramatically every semester. Not knowing exactly who we represent at all times makes it difficult to sign up new members and impossible to ensure UIC is deducting dues correctly.

In August, GEO discovered that the university had mistakenly deducted dues from sixty nonmembers, individuals we had never claimed were union members in the first place. Mistakes like this put the union at legal risk, since the erroneously deducted money goes into our local’s bank account and makes the local liable for “taking” it. We alerted the administration immediately and they quickly corrected the error. What we still haven’t been able to figure out is why a handful of grad workers, overwhelmed with our normal teaching and research responsibilities and representing our union as volunteers, have to tell well-paid administrators at a multibillion-dollar institution like UIC how to do their jobs.

All of this comes as our unions are in the middle of contract negotiations. Even before Janus, UIC was already prone to bullying campus workers at the bargaining table and pushing us into going on strike. In 2014, faculty with UICUF had to strike to win their first contract. Last fall, the INA-represented staff nurses and administrative nurses at the UI Hospital came within a hair’s breadth of walking off the job before an eleventh-hour agreement was reached. This past spring, grad workers at the Urbana-Champaign campus had to strike for nearly two weeks in order to safeguard tuition waivers.

It comes as no surprise, then, that the administration has tried to exploit the post-Janus confusion around dues deductions to gain an advantage in bargaining, presumably to pressure us into making concessions on issues that matter to our members in exchange for the continued existence of our unions. When GEO first questioned why the administration had not deducted July member dues, they said they would only discuss it with us in contract negotiations—never mind that abiding by existing contract language and existing law is non-negotiable.

UIC grad workers—whose baseline pay is only $18,000 and who are forced to pay up to $2,000 in fees every year—are fighting for living wages and fee waivers. UIC’s tenured and nontenured faculty are fighting for increased job security, shared governance, and raises. That should be the focus of negotiations, not bureaucratic procedures around dues deductions.

The administration is waging its most vicious attack on the underpaid Licensed Practical Nurses (LPNs) with INA at the UI Hospital, who have also been in bargaining since Janus came down. Shortly after the ruling was issued, the university decided to bring in a new lead negotiator, who proceeded to tear up previously agreed-upon articles and introduce extremely regressive proposals in their place. Among other things, UIC is demanding LPNs surrender their right to engage in virtually any kind of concerted activity at the workplace, while demanding INA publicly disavow any kind of protest carried out by its members and threatening to single out union leaders for discipline.

UIC administrators seem to have assumed that Janus would leave our unions weakened and afraid, allowing them ride roughshod over us and impose terrible contracts. But they miscalculated.

Thanks to the administration’s handling of Janus, the campus unions are working together closely. In late July, members of INA, UICUF, SEIU Local 73, and GEO held a joint march on the boss, showing up unexpectedly at the office of the head of university Labor Relations to demand accountability around the failure to deduct dues. Clearly rattled by this, the administration has since been far more careful around processing deductions and correcting errors when we point them out.

Meanwhile, all of our unions have filed or plan to file both grievances and Unfair Labor Practice charges. GEO and UICUF are ramping up our respective contract campaigns, both building towards possible strikes next spring which might easily coincide. This week, the LPNs will be going out on an indefinite ULP strike, and members from all four of our unions will hold a unified protest and rally as the UIC Board of Trustees gathers on campus for a meeting.

The budding coalition of UIC unions should be on every labor activist’s radar, as it’s emblematic of what a post-Janus world can look like for public-sector unions: a huge uptick in hostility from the boss met with more solidarity, more organizing, more direct action, more strikes, and a deeper determination to fight for our rights as public sector workers to ensure our students get the education they deserve, and our patients get the care they deserve.
