They can send you a corrective action any way they choose, I suppose, but it's not valid if you don't sign it. Make sure if you are getting written up for not meeting a sales goal, that you do keep track of these ridiculous goals just in case you need to prove your case. Honestly, we did a lot better last year when we just followed the Daily Sales Report for sits and sales. Something to try to reach clumping days together. How unrealistic.
In my area, people don't have disposable income like they do in the bigger cities. I do expect to see an increase a bit right now because of people getting tax refunds but there are people who would rather buy large screen tv's and a fridge full of beer before they spend any money to get their kids pictures taken. Sad, but true!
