I read an article that Kroger posted a loss for the first quarter this year. Seems to match up with the pause in the mystery shopping jobs. Plus, I've been hearing the employees talk about a vote for a new contract. Mystery shopping reviews are not favored by many working there.
Do not read so much, look about you and think of what you see there.
