If an individual has had issues with work and signed off sick through stress and then is trying to claim injury to feelings-do they have to prove some form of discrimination before this? Individual is head of HR and has thrown their dummy out because they weren't considered for a partnership role. Company has an incredibly specific line of work, HR cannot do any of this work and never would be able to (think professional vocation), partners have never been anything other then those carrying out the work of the company and HR head just got this idea themselves. Individual has caused problems since day one in the role and lost clients and caused long term staff members to resign. Has had numerous occasions of walking out in a strop because things aren't going their way. Has an illness that they have always claimed doesn't impact on their work and has always been allowed time of for appointments etc and asked if any changes are needed to accommodate this-has always denied anything needed doing. Now after resigning trying to claim unfair dismissal and injury to feelings. But does a specific discrimination have to be proved or can this be done on its own?
