Thank you. If you are considering constructive dismissal you 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 you 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.
With either the constructive dismissal or age discrimination claim, a new feature in the employment tribunal’s claims process is mandatory early conciliation with ACAS. This requires prospective claimants to notify ACAS and provide details of their intended claim and they would then try to negotiate between the claimant and respondent to seek out of court settlement in order to avoid having to take the claim to the tribunal. It is possible for the parties to refuse to engage in these negotiations, or that they are unsuccessful, in which case they would get permission to proceed with making the claim in the tribunal.
If negotiations are initiated and settlement is reached, then the claimant would agree not to proceed with the claim in return for the agreed financial settlement.
The conciliation procedure and the form to fill in can be found here:
In terms of the time limits within which a claim must be presented, the early conciliation process places a ‘stop’ on that and the time between notifying ACAS and them issuing permission to proceed with the claim would not count for the purposes of these time limits.
