Cornerstone Resources offer workplace mediation services for Manchester businesses

Workplace conflict costs UK employers roughly £1,000 per employee, equating to £28.5 billion every year. For most businesses, that cost doesn’t arrive all at once. It accumulates under the radar, through management hours, sickness absence, reduced productivity and the kind of team atmosphere that no one mentions in a team meeting, but everyone feels.

In response to this, Cornerstone offers TCM-accredited workplace mediation services to businesses across Greater Manchester and beyond.

Mediation before it becomes a grievance

The instinct for many organisations is to reach for a formal grievance process at the first sign of a serious dispute. It’s understandable, but it can be expensive and, in many cases, unnecessary.

A formal grievance costs roughly 4.5 times more to resolve than mediation. At an average cost of £1,917 for mediation versus £8,775 for a formal grievance process, the financial case is straightforward.

The human case is equally compelling: formal processes tend to harden relationships rather than repair them, leaving both parties resentful long after a decision has been reached.

Workplace mediation takes a different approach. It’s confidential, voluntary and impartial. Both parties are given the space to be heard properly, to understand each other’s perspective and to agree on a practical path forward. Most mediations are completed within a single day.

Cornerstone’s mediators are professionally trained and accredited through the TCM Group, one of the UK’s leading workplace resolution organisations. Their approach is honest about when mediation is and isn’t the right fit: where serious allegations require a formal investigation, or where criminal conduct is involved, they’ll say so and help identify the appropriate course of action.

Training managers to handle what comes next

For situations where a formal process is unavoidable, Cornerstone also offers practical online training for managers on handling workplace investigations and disciplinaries. The two-hour session is aligned to the ACAS Code of Practice and covers everything

from when to intervene informally through to running a fair disciplinary hearing. The next open session runs on Thursday 9 July 2026, priced at £595 + VAT per organisation.

When to consider mediation

Mediation tends to work best where the core issue is relational rather than disciplinary: a personality clash between colleagues, a breakdown between a manager and a direct report, communication failures that have started affecting team performance, or tensions arising from organisational change.

If you’re uncertain whether mediation is the right route, or whether a different approach would better suit the situation, Cornerstone will give you a straight answer.

Conflict left unaddressed rarely resolves itself

For businesses in Greater Manchester dealing with a difficult working relationship or an unresolved team dispute, early intervention is almost always more cost-effective than waiting. A well-handled conversation now is usually far preferable to a three-month grievance process and two resignations! Cornerstone’s conflict resolution guide for employers covers the full spectrum of approaches available, from early management conversations and facilitated discussions through to formal investigations and grievance procedures.
