Can a business threat to cut your pay if you don't retire?
A business can make pay cuts to the wages of positions within the company.

However, if you are in the same position as someone else and still fulfilling your job duties you must be compensated accordingly.

The threat to cut your pay if you don't retire doesn't really do much - if they do cut your pay and not others similiarly you may have an age discrimination case.

Most threats are just for intimidation - just stay put and let this business either do the right thing or hang themselves
