A new FA "Fact Sheet" makes the argument that the administration's imposed "Reduction in Force" language would essentially end tenure on this campus.
These terms would make for a radical change from the prior contract, which allowed for layoffs of tenured faculty only in the event of program elimination or "just cause" (i.e., serious misconduct). The last contract even included a side-letter saying that the administration would not lay off faculty on the grounds of financial exigency. Now they are claiming the authority to lay off faculty even without the messy PR and fiscal consequences of declaring a financial exigency. If you can be laid off at the sole discretion of the administration, your tenure isn't worth a damn.
Tenure is an essential part of academia as most faculty understand it. These terms, therefore, are poison. If not withdrawn or massively modified they will result in a strike. I think it's as simple as that.
