I am being bumped off shifts by a retiree

The concept of "retirement age" is misleading. You can chose to collect Social Security payments anytime between age 62 and 70. (Assuming you have worked and contributed for 40 quarters). But, the monthly payment increases the longer you put off starting. You get "full Social Security" at age 66, if you were born before 1954, and somewhat later if you were born after that. But, "Full Social Security" is really arbitrary, and is certainly not enough for everyone to live on. Since the benefit is so small, it really is wise for people to put off collecting Social Security to the point where it will best meet there needs, if they are healthy and wealthy enough to put it off.

So, don't assume an older co-worker can retire. "Trying it once and being bored" may be a euphemism for being unemployed late in life, a situation many of us have found ourselves in.
