I have been employed with the same company for 31 years. My hours have suddenly been reduced from 40 to 30. Is this a case of constructive dismissal

The reduction in hours and corresponding reduction in pay amount to a constructive dismissal. You need to contest the negative change because if you do not it will become a term of your employment and your termination entitlements will be based on 30 rather than 40 hours per week. Another issue that arises is whether or not you are obligated to continue working there and I do not have all the facts to make that determination.
