If an employee doesn't fit in with the culture just because of their age, than the culture is the problem, not the employee. You've just described something that actually is pure age discrimination: maintaining a company culture in which there is no room for people above a certain age, regardless of their skill, knowledge, personality and other qualifications. Edit: Just to clarify: nobody "doesn't work well with everyone else" because of their age. That is a bogus argument, a clear sign of age discrimination.
