after high school graduation, you decided to work full-time for a year before beginning college. during that gap year, you worked at a grocery store stocking shelves. while there, you joined a union. you are now applying to work as a part-time salesperson at a furniture store while attending college. at your interview, you are asked if you were ever a member of a union. when you respond yes, the interviewer advises you that the store does not hire anyone who has joined a union and promptly ends the interview. you receive a letter two days later telling you that you were not chosen for the job. you think it is unfair that your prior union affiliation disqualified you from the job at the furniture store. did the furniture store commit an illegal act by failing to hire you because of your prior union membership?
