Employment Contract Loss Expert Witness

Employment contract disputes involving senior executives, sales directors, and financial professionals frequently require expert evidence on the quantification of financial loss. Wrongful dismissal claims in the High Court (where contractual damages exceed the employment tribunal jurisdiction) focus on losses during the contractual notice period, salary, guaranteed and discretionary bonus, pension contributions, LTIP vesting, car allowance, and other benefits that would have been received but for the employer's repudiation of the contract. Expert witnesses calculate these components precisely, addressing the contractual mechanisms governing bonus entitlement and the evidential burden on each party.

Restrictive covenant breach claims require a different analytical approach. Where a former employee breaches non-compete, non-solicit, or non-dealing covenants, the employer's loss is the revenue and profit diverted to the competing business or poached from the employer's client base. Expert witnesses trace diverted transactions using CRM data, client lists, comparator market analysis, and, where disclosed, the competitor's own financial records. The analysis distinguishes between revenue that would have been lost in any event and revenue directly attributable to the covenant breach, applying appropriate profit margins to arrive at the net loss figure.

Garden leave disputes, bonus forfeiture clauses, and long-term incentive plan termination raise additional quantum issues. Expert evidence may address whether the employer acted in breach by excluding the employee from bonus pools or accelerating forfeiture provisions, and quantify the financial impact. While employment tribunal claims for unfair dismissal follow a different remedial framework, contractual claims in the civil courts and commercial arbitration demand the same rigorous but-for analysis applied in general commercial litigation, adapted to the specific compensation structures found in executive service agreements.
