Downs folks often see early onset alzheimers in their late 40s and 50s. So perhaps he could no longer do his job?
All sentiment aside, this just might be the case. The manager could have been nicer about it, but many states give employers the right to fire “at will”.
He may say he wants a retirement party but when that party is over, this guy will probably need something else to fill his days routine.
He may not really understand what retirement often means.
Valid point. Was talking to a friend last night, asked about her brother who has worked at Home Depot for maybe 20 years and is in his 50's. He operates at perhaps a 5 to 7-year-old mentality and ability, and lives with her. She says he is now open to fits of anger when things don't go his way, and his outbursts are getting worse in his 50's. Hopefully that doesn't happen on the job at Home Depot. It's a concern not just about ability to do the job, but keeping a peaceful environment for co-workers and customers.
