Is this change to contract terms allowed?

[Ben1987]

Hi,

Hopefully someone can help me regarding an issue I'm having. It's a bit of a complicated story so apologies for the long description.

I started a new job last week (19th Jan). I was offered this job around the start of December and received my contract, which I signed and returned to my new employer. The grade of my role that was stated on my contract was G4, which entitled me to certain benefits, higher pay and 27 days a year holiday.
Since starting there last week I noticed my online profile stated that my grade was G3. I spoke to my manager and he said that I was supposed to be offered a G3 grade for my role, but HR have accidently sent me the wrong contract. Now they are wanting to reduce my grade down to a G3, which will affect my benefints, holiday and potential for pay rises and bonuses.
My question is, are they allowed to change my contract that drastically? There is a clause saying they can make resonable changes, but in my opinion this is that resonable, bearing in mind that I wouldn't have accepted the job on the basis of a G3 grade as it would have been the same as my previous role.

Hope that all makes sense, and thanks in advance for any help!

Your employer has breached a fundamental contract term.

The employer should have, as expected, proof read the contract before issuing it to you and this is the company's fault which should not have a detrimental effect on you. They cannot simply 'make reasonable changes' when it concerns a significant term and goes to the root of the contract.

Such a breach will entitle you to claim constructive dismissal and to seek a remedy via an Employment Tribunal.

However, you*need to show some actual loss suffered by the breach of your employer before any award of damages is made.

Just be aware that an employee usually needs two years continuous service with their employer in order to pursue a constructive dismissal claim against them

and i realise for training and thread is 4 years old

Perhaps some arithmetic training?* *5+ years old

Ive been in a very similar situation recently! Accepted a new job and my contract was changed quite drastically. Currently seeking advice on where I stand. Will keep you updated.
