The document summarizes a judgment from an employment tribunal case between Mr. Douglas Gardiner as claimant and Exsto UK Ltd and others as respondents. It discusses the allegations made in the case regarding constructive unfair dismissal, race discrimination, disability discrimination, and unpaid wages. It finds that while some of the claimant's longstanding complaints predated the key issues, the respondent company's actions from December 2010 did amount to a fundamental breach of contract justifying the claimant's resignation. However, it also notes that the company later made some deductions from the claimant's salary in an attempt to undermine his claims, which were not part of the original issues and aggravated the situation.
