This worries me 3 ways:

• shifts longer than 8 hours show significant attention span issues
• you didn’t specify day or night shifts, the latter of which is massively detrimental because of the circadian rhythm and altering your day vs night
• maybe the job didn’t specify, and that’s worse

Worst of all would be a 2-2-4 day/night/off schedule, as that combines a too-long shift, a wake-sleep change, and then a too-long shift in darkness.

This kind of job spec, unless they specify it’s only mildly damaging, could be the most toxic format of all!

P.s. I can’t believe I’m wishing for it to be the minimally-toxic-but-still-fucking-toxic 4x12 daytime slog.
