I workws for a small software development company (18 employees), and we were acquired last summer by a huge corporation (4 Billion in sales, traded on the TSX, over 4000 employees, etc...). I am currently in my 15th year of employment with this employer.

As part of their restructuring they have changed people's work assignments and compensation plans.

In my case, my position has expanded in scope and responsibilities quite a bit (I used to oversee a territory of about $800,000 in contracts, and now oversee all company contracts worth about 2 million dollars and have gone from managing 87 clients to over 200), however the new compensation plan has actually lowered my annual take home pay by about 23%

They are pressing me to sign a new contract approving this change in job scope and compensation, however I don't think this would be in my best interest and they should go back to compensating me based on my original contract.

What are my options here?
