Getting through a block of shifts

Most shift advice is strategic: rotations, sleep hygiene, long-term health. This is the tactical version — what to actually do across four consecutive shifts, from people who have worked a lot of them.

The day before

The block is substantially decided before it starts.

Sleep properly. Deficits compound forward, so starting short changes everything after it. This is the single highest-value hour of the whole block, and it is the one most often given away to a social event at the end of several days off.

Prepare the food. Four days of meals, portioned, ready. Prep on the last day off, not on a weekday, so it is freshest when your capacity is lowest.

Do the admin. Fuel, laundry, bins, the phone call you have been avoiding. None of it will happen during the block.

Set everything out. Uniform, bag, keys. On day four you will be assembling yourself on autopilot and every removed decision helps.

During

Eat at a decided time, not when there is a gap. A gap will not appear. Deciding in advance when the break is, and taking it, is the difference between eating properly and eating a chocolate bar at 15:00.

Protect the sleep between shifts ruthlessly. Nothing social, nothing that runs late, nothing that requires a decision. The block is not the time.

Drop your standards at home, deliberately. The house does not need to be tidy across four working days. Trying to maintain a normal home life during a block is how people arrive at day four with nothing left.

Front-load anything cognitive. Whatever needs judgement, do it early in the shift and early in the block. Error rates rise in the later hours of the later shifts, and the self-assessment goes first.

The last shift

The hardest one and the one where mistakes cluster.

Expect to feel worse than you are performing, or better. Neither self-assessment is reliable by shift four. Check things you would normally not check.

Plan the journey home before you start. If you drive, decide in advance whether you will nap first. Deciding at 07:30 while impaired is the wrong time to make that call.

Do not agree to a fifth. The offer usually comes at the end of the fourth, and it is made to someone in no position to evaluate it. Decide your limit while rested and hold it.

Coming out

Sleep first. The instinct is to salvage the day. It does not work, and it costs the following day too.

Treat day one as recovery, not as a day off. This is the single most common source of disappointment in shift-working households — a calendar showing four free days that is really three. Make it visible so nobody, including you, plans against a picture that was never true.

Get daylight when you wake. Whatever time that is, it helps re-anchor the clock for the days off.

Do the easy things on day one. Not admin, not difficult conversations, not a long drive.

What to fix if a block keeps going badly

If blocks are consistently harder than they should be, the usual causes in order:

1. Not sleeping properly before the first shift. Fixable and most common.
2. Eating badly during it. Fixable with preparation on the day before.
3. Taking overtime on block edges rather than on rest days.
4. Trying to have a normal home life during it, which is where the last of the capacity goes.
5. A rota problem — insufficient rest between blocks — which is a conversation with a manager rather than something to solve personally.

The first four are yours. The fifth is worth raising rather than absorbing.
