Mitrefinch found interest in trade unions from hospitality workers has declined by over half (58%) since 1995 to just 3.3% in 2018.
The research shows around 3% of the hospitality sector is unionised compared to 17% of the manufacturing sector and 35% for the transport sector.
Julie Lock, commercial director at Mitrefinch, commented: “The analysis demonstrates a worrying decline in the percentage of hospitality employees engaging with trade unions across the UK.
“With the support which trade unions can provide to employee wellbeing and engagement, this decline in data points to signs that employees may soon be navigating this alone.
“It is important for hospitality firms to continue to support the wellbeing of their employees in these sectors where trade unions are becoming less prevalent, especially with the additional worry which the pandemic has caused for workforces across the UK.”
