Carers, lollipop people, school dinner servers and cleaners will all get their glad rags on to attend the Cordia awards dinner.
A total of 13 awards will be presented at Kelvingrove Art Gallery and Museum tomorrow night for care services, facilities management, hospitality and management.
David Melvin, managing director of Cordia, said: "This annual celebration is a particular favourite of mine as it allows both the Cordia board and the senior management team the opportunity to pay tribute to our staff.
"Their hard work and commitment, often volunteered above and beyond what is required of them, characterises all that is great about Cordia and its subsidiaries.
"Not only are my colleagues - all 7300 of them - crucial to the continued success of the organisation, they are also the heartbeat of our city."
This year has seen a record 1669 entries to the competition.
Clyde 1's Knoxy is on presenting duties for the event.
Catering assistant Anne Marie Traynor, from Bridgeton, is up for her third Cordia recognition award, having won in 2010 and 2012.
The 46-year-old said: "It's really nice to be nominated, but I don't want to jinx my chances of winning the award three times. I'm lucky as I really like my job and love working with the kids."
Also up for a gong is school crossing patroller Jim Solokov, from Baillieston, who helps pupils from St Benedict's and Oakwood primary schools as well as Lochend High School.
The retired bus driver wanted to help in his community and began working for Cordia four years ago.
Jim, 70, said: "From the amount of grandchildren I have it is no understatement to say I love kids. Besides, I didn't just want to sit about and do nothing."
Siobhan O'Brien, a home carer, has worked with Cordia for two years and is also a student, working towards a geography degree from Glasgow University.
Rather than get a bar job, the 22-year-old wanted to try something different.
Siobhan, from Cumbernauld, said: "I get on really well with my clients and it's lovely to spend time with them. Many of them have such fascinating stories, so it's great to just be able to listen to them."
