My company offered to lay me off instead of taking a pay cut. Then changed their mind a week later.

My company was giving pay cuts to its employees. If an employee got a pay cut above a certain percentage, he or she could choose to take a lay off with severance pay and collect unemployment insurance. I was told that I fell into that category and I made plans to get laid off in the next month.

Almost a week later, I was contacted again and was told there was error and my pay cut was smaller than they originally thought. The problem is that the lay off was no longer an option for me. I would now either have to quit without severance pay and unemployment insurance, or remain with the pay cut.

This didn't seem right since I already made plans to be laid off based on the information they gave me. Is there anything I can do?
