The tribunal, which was due to be held between Friday, October 9 and Friday, October 23 in Leeds will now not take place.
An East Riding of Yorkshire Council spokesman said: “The council implemented a process of restructure within its Culture and Customer Services Division, which led to changes and regrading of posts including Mr Aldis’, which he found unacceptable.
“It is acknowledged that this was a source of unhappiness to him and regrettably resulted in an unresolvable dispute.
“Mr Aldis’ employment was terminated by the council in October 2019 and of course we regret any distress caused to Mr Aldis as a consequence.
“We recognise and pay tribute to his 10 years’ commitment and dedicated service; which has not only seen Bridlington Spa raised to national significance but has also provided a springboard for young people wanting to work in the arts. We wish him the very best for the future.”
Mr Aldis said: “I would like to thank East Riding of Yorkshire Council for recognising my contribution and achievements at Bridlington Spa. I always believed that the re-evaluation of my post was not right.
“Whilst I will always consider the council’s decision to be wrong, I simply cannot continue being angry. This last year has taken its toll and it is time to put the story to bed.
“Representing Bridlington Spa and the town for 10 years has been an honour and a privilege. I have many great memories and very few regrets.
“There are hundreds of people who have made my time here special; which has led me to call this part of Yorkshire my home. I will continue in my endeavours to find future employment here.
“I hope I will be remembered as a person who showed commitment, who was always open and honest, who fought for the town whilst driving change and innovation and as someone who had the courage to speak out in order to make things better.
“Above all, I would hope to be remembered with fondness.”
