Long one; sorry.
The way it worked when employed last job, you had to qualify for the health insurance. Just work a year's worth, but they didn't "dispatch" you when you got close to the hours, so for a lot of us, it took 2-3 years. You were on it while working, but we worked week-on-week-off. Once you qualified for "permanent" relief employee, the week off was considered "employed", because you worked 84 hours a work week = 2 forty hour work weeks. Could take 1-2 year.
The health Insurance had disability, but required doctor's certification. It was good until you started getting Social Security disability, or became fit-for-duty (requiring a doctor's certification). If you became "fit-or-duty")" and didn't tell the employer, you had to pay back the amount for the length of time you became fit-for-duty, again, and failed to tell employer.
Sometimes, the employer used an investigator, and took photos allegedly showing you were fit-for-duty.
Your disability could be judged buy the US Coast Guard, and they suspended your license or working papers. The Employer had to accept that. (We were Mariners = Merchant Marines. You don't work on a US ship until you pass their tests and required private company's training and had a letter of future employment from an employer. Or the employer could have the training.) Knews a guy with an artifical leg from above the knee & he was still working. Doc & USCG said he could.
If you retired, then the employer's disability stopped when you reached 65.
If you qualified for Social Security disability, the employer's disability stopped. You could work when over 65.
Easy for employer's disability. Employer disability better than SS, which depended on your Gross Earned Income for the previous 3 year's worth of work, divided by 3.
Social Security hard while they had the secret rule in effect to deny applicants though the 1st 2 stages. Once that rule leaked, lawyers had a heyday, and employer put out a pamphlet on how to do it and how to get a lawyer to force SS to do it, if it got to that. SS reformed - they lost case after case, and that meant they paid your lawyer (hehehehehehehe).
I dealt with people in every possible variety of those situations to help them straighten it out. If they weren't qualified, I took the blame. (Sigh)
I don't think I ever heard of incontinence as a disability - but our medical records were a protected secret, and we didn't know why & what unless the person told someone, or gossip from on-shore reached us. That was also never on the Accident Report, but that may not have been included by the doctor on that form. I saw every Accident Report for 9 years, 650 employees. I never heard of that one, even by rumor. It seems like there had to be an example, say fecal?
Most "staterooms" for employees were singles, so no roommate to give it away. You emptied your own trash can, bathrooms/showers down the hall. You had a washbasin.
My incontinence wasn't until after I was retired for a few years.
