Ok thank you for clarifying. You will have certain rights and these will very much depend on what your contracted position is. For example, if you had a written contract in place which said that you are a waiter and it did not mention anything in there about the employer’s ability to move you around, change your job and so on, then asking you to move from being a waiter to being a chef would amount to a breach of contract.
Even if you did not have a written contract in place, if it was always understood that you had taken on the waiter job on a permanent basis, the same rules would apply and being moved to another position when you were supposed to be working permanently as a waiter would amount to a breach of contract.
This could potentially amount to constructive dismissal, which occurs when the following two elements are present:
- Serious breach of contract by the employer; and
- An acceptance of that breach by the employee, who in turn treats the contract of employment as at an end. The employee must act in response to the breach and must not delay any action too long.
A common breach by the employer occurs when it, or its employees, have broken the implied contractual term of trust and confidence. The conduct relied on could be a single act, or a series of less serious acts over a period of time, which together could be treated as serious enough (usually culminating in the 'last straw' scenario).
The affected employee would initially be expected to raise a formal grievance in order to officially bring their concerns to the employer's attention and give them an opportunity to try and resolve them. If the issues are so bad that the employee can't even face raising a grievance and going through the process, or if a grievance has been raised but has been unsuccessful, then they can consider resigning straight away.
If resignation appears to be the only option, it must be done without unreasonable delay so as not to give an impression that the employer's breach had been accepted. Any resignation would normally be with immediate effect and without providing any notice period. It is advisable to resign in writing, stating the reasons for the resignation and that this is being treated as constructive dismissal.
Following the resignation, the option of pursuing a claim for constructive dismissal exists. This is only available to employees who have at least 2 years' continuous service. There is a time limit of 3 months from the date of resignation to submit a claim in the employment tribunal.
An alternative way out is to approach the employer on a 'without prejudice' basis (i.e. off the record) to try and discuss the possibility of leaving under a settlement agreement. Under a settlement agreement, the employee gets compensated for leaving the company and in return promises not to make any claims against the employer in the future. It is essentially a clean break, although the employer does not have to agree to it so it will be subject to negotiation. In any event, there is nothing to lose by raising this possibility with them because you cannot be treated detrimentally for suggesting it and it would not be used against you.
Just to make a final, yet important point, that constructive dismissal can be a difficult claim to win as the burden of proof is entirely on the employee to show the required elements of a claim were present. Therefore, it should only be used as a last resort.
Hope this clarifies your position?
