no, apple is currently conducting negotiations with the unionized store and there is no contract so presumably they are working on getting that into the contract as part of the bargaining process. which is literally the way unions are set up to work.
messing with existing benefits could be construed as an intimidation tactic but delaying new ones due to going through the union workers just voted in is not, since the union has already been elected this isn't interfering with a vote or sm.
