Older engineers whose salaries have finally doubled in purchasing power over the salary they earned just after graduation from engineering school are barraged with signals from management that they are not wanted. Older computer systems stayed relevant for years, some for a full decade or more. So people who used those systems know a lot about them. Older people should be supported in coming to meetings and given briefings before meetings, and the use of jargon should be avoided. Group members should also be given the chance to get to know one another. Age discrimination at work only harms the company.
