Your employer provides you with a written description of your benefits when you begin. It says you will get 2 weeks vacation aft
er your first year. At the beginning of the second year, he tells you sales are way down, you are a wonderful employee, and that he simply can't pay you the vacation he promised you, and besides, you are too valuable to do without for two weeks. You demand your vacation. Can he legally say "sorry, no vacation."????
A contract of employment is a legal binding that exists between an employee and his staff. None of these parties has no right to change the contract just on their own accord. If a change has to occur it must be on mutual grounds between the employer and employee. A one-sided variation is a breach of the contracts of employment and this makes it illegal.
Depending on the extent and impact on the job, the employer should meet with you and explain their case for making these changes.
