What's the most challenging job to keep?

Non-union electricians. According to a friend of mine, when it comes to roughing out houses, the mantra is “Three a day or on your way”.

Show runner on any network TV series. They are prone to getting cancelled or replaced in the blink of an eye. In fact, there was once a series that was cancelled before it even finished airing.

What is a “show runner”?

I’ve got one for you - senior fundraiser for a major charity. Not the folks who stand on street corners hassling for your money, but the ones who look after major corporate and individual donors.

Generally, the charitable sector doesn’t pay well, but competition for good fundraisers is stiff, so to have chance of recruiting you have to pay them well. Therefore because they are costing you more than 99% of their staff, you want a return on your investment pretty much straight away. If they’re not bringing in cash by your 6 month probation meeting, chances are they’re getting canned.

Not that the successful ones stick around much longer - generally after a year or so they’ll move on to pastures new, for more money. It takes on average two years for a charity to make a profit from a senior fundraiser, especially as recruitment costs are usually also high, but the average length of service is a lot less than that.

Leader of any democratic country is a pretty challenging job to keep.

Showrunner.

Basically, the showrunner runs the show. Even though TV shows have directors for each episode, you could say the showrunner’s power/influence is much closer to that of the director on a movie set. Famous examples would include Vince Gilligan on Breaking Bad, David Benioff on Game of Thrones, etc.

You’re right in general about commission-only jobs. But car sales is notoriously low-security. It’s always “What have you done for me lately?”

I’m including the sales managers in that group, by the way. Little security, lots of pressure, lots of ulcers.

Associate professorship (tenure) in a humanities department at a highly-competitive university. Five to seven years and you’re out, unless you’ve achieved publishing superstardom while managing to not piss off the tenured profs who vote on your tenure.

I’ve always thought that car sales would be a difficult job to persist in (due to dependence on commissions and the requirement to be slimy to make a living and/or endure rude buyers who think you are slimy (even if you’re not).

The vast majority of porn actresses do one video and then drop out of the industry. So that is a field with a pretty low retention rate. If you are looking for fields with a more socially acceptable title, I would think some high finance jobs can be pretty stressful since you are constantly under pressure to make your numbers each quarter.

Also low paying service sector work, turnover can be 40-50% a year in those.

Really? The vast majority? Just ONE? Out of curiosity - have you worked a porn, or do you have a source for that? (besides being a consumer of it, naturally)

Not trying to be a dick or anything, but I’m really curious if that’s actually true.

City managers tend to have short tenures. Firing comes with the territory, and many leave even when they might be in good standing, to fill the positions of others that were given the boot.

How about US House representative? They have to campaign for reelection every two years. Even senators get something of a break.

I’ve personally seen two low-rent jobs that are brutal in terms of survival.

Call centers, whether they’re telemarketing or customer service typically have extremely high quotas for sales and/or call volume. You have to follow the script, and complete the call in X time. Pray that you don’t call someone who stutters - that person can blow your average for the whole day.

When large retail stores open, they typically hire more staff than they’ll eventually need. After a month or so when the “new” wears off they cut staff to a more sustainable level.

I’d estimate the odds of lasting more than a month at either job is probably less than 50% even if you don’t screw up.

The only job like that I can think of is a stockbroker like you see in the film Boiler Room. The company will typically hire a bunch of ‘trainees’ right out of school and pay them nothing for a few months until they pass the Series 7 exam. Then it’s basically sink or swim trying to sell their own accounts. I went on an interview at one of those places when I was right out of school. The guy said about half the people you see on the floor won’t be there in a 6-12 months.

Did you mean assistant professorship? An associate professor already has tenure, at least in the US universities that I know of.

That is not a job.

Failure rate for 9-1-1 trainees can be 75%. If you successfully complete training the job stress is extreme. Calls are reviewed regularly and anything less than perfect is criticize. Retention rates can be pretty low as a result.
