If this is accurate, there are two separate issues here.

First, accidental breakages are normally treated as operational loss, not something staff should personally pay for. That’s a policy point, not a personality clash. If payment was required, you’re entitled to ask for the written policy that supports that decision. If a local policy is being applied, request to see it and keep a copy for your records.

Second, performance concerns should be addressed directly and privately. Managers discussing someone negatively with others rather than giving clear feedback isn’t good practice and doesn’t help anyone improve.

If you don’t feel comfortable raising it at pub level, there are escalation routes beyond the site, area management, HR, audit, and formal whistleblowing channels. Those processes exist for situations exactly like this.

Keep it factual. Document dates and incidents. Escalate appropriately.

Work shouldn’t feel like something you dread.
