Advice on weekend sleep

Where tf do you work why are you putting in that many hours

Nah bro you should be asking for advice on lateraling. That's crazy

7am-4am regularly would mean you have 3 hours for sleep per night (realistically, including getting ready for work, commuting, and ready for bed, you'd get under 2 hours). You would not survive that, physically, for more than a couple weeks without serious health issues.

This is also 100 hours per week in 5 days which I've never heard anything remotely close to that outside maybe a one week sprint, even at the worst shops. Hard to buy any of this.

Dude do you have Stockholm syndrome?

If you’re on by 7am everyday that’s by you’re own volition. Sometimes there’s a fire drill but otherwise I’m not checking my email until 8:30 and nobody is expecting me to respond before 9 - let alone have something turned by then (unless you didn’t finish your work the previous night, which is a you problem).

Ending at 4 am everyday is likely another you problem. You need to ramp up better or something is wrong - I highly doubt any associate is asking you for new tasks after midnight, and most seniors above that are trying to sign off by 11pm at the latest. Of course there are fire drills, but no this is not likely every fucking day.

So likely you are either “not getting it” which makes you painstakingly slow or if the above is all true (which I doubt considering this is GS13 during the Covid boom level of sweat) - you should lateral asap.
