Scale

Shift rosters: 12x36, 24x48, night shifts and planning your month

The scale arrives in different formats in each place: 12x36 in one hospital, 24 hours in another, on call on the weekend. Understanding the notation and adding up the hours of the month avoids time shock and accumulated fatigue.

What each scale means

The first number is the working time. The second, the rest time until the next turn.

  • 12x36: 12 hours on shift and 36 hours off. E.g.: shift from 7am to 7pm on Monday, returns on Wednesday at 7am.
  • 24x48: 24 hours on shift and 48 hours off.
  • 24x72: 24 hours on shift and 72 hours off.
  • Notice: you are available to be called, without being on site all the time.

Night shift

The shift from 7pm to 7am starts one day and ends the next. It's just a 12-hour shift. In the spreadsheet he usually turns two lines or a wrong calculation (7 minus 19 is negative). When adding up the month, count by duration: from 7pm to 7am are 12 hours.

How many hours do you work per month

Adding up the hours helps you see the real size of the routine. Example of a month with three locations:

  • Hospital A, 12x36 daytime: 8 12-hour shifts = 96 hours.
  • Hospital B, 2 shifts of 24 hours = 48 hours.
  • Clinic, 4 mornings of 6h = 24 hours.

Total: 168 hours in the month, not counting travel.

CLT, PJ and self-employed

For those who work with a formal contract, the 12x36 working day is provided for in the CLT (art. 59-A) and depends on a collective agreement or convention. For those working as a business or self-employed, the scale is what was agreed with each location. If you have any questions about your contract, seek legal advice.

Exchanges and cancellations

  • Record the exchange with the colleague's name and the date you took over.
  • Before accepting the change, check that the new schedule does not overlap with another commitment.
  • A shift canceled by the location means revenue that doesn't come in: make a note so you don't expect payment.

Rest between shifts

Two consecutive shifts in different locations may fit the role and not fit the body. Before accepting an extra, look at how many hours are left between the end of one and the start of the other, counting the journey. When working with a team, arranging breaks during the shift also helps.
