In Saint Vincent and the Grenadines, the standard working hours are established by the Minimum Wage Regulations, 2003, under the Labor Act. These regulations set different hour limitations depending on the industry and worker classification.

For general workers, as defined in the regulations, they are entitled to a maximum of 8 hours per day and 48 hours per week.

The regulations specify variations for specific sectors:

• Agricultural Workers:
  • Sheltered Workers (working indoors): Maximum of 9 hours per day if provided with living-in accommodation.
  • Unsheltered Workers (working outdoors): Maximum of 6 hours per day if not provided with living-in accommodation.
• Domestic Workers:
  • Without living-in accommodation: Maximum of 10 hours per day, including 2 hours for rest. Sundays or Saturdays (depending on religious observance) and public holidays have a reduced maximum of 6 hours.
  • With living-in accommodation: Maximum of 11 hours per day.
• Nursing Home Workers: Standard working hours are set at 8 hours per day and 48 hours per week.

In Saint Vincent and the Grenadines, employers are required to pay overtime wages when an employee works beyond the standard hours. The overtime rate is one and a half times (150%) the regular hourly rate for every hour or part thereof. Work performed on Sundays and public holidays attracts a higher overtime rate: double time (200%) the regular hourly rate for every hour or part thereof.

In Saint Vincent and the Grenadines, specific regulations are in place regarding rest periods for domestic workers. These regulations are outlined in the Saint Vincent and the Grenadines Statutory Rules and Orders 2008 and vary depending on the living arrangements and job type of the worker.

For domestic workers who reside with their employers (live-in arrangements), the total work hours cannot exceed eleven hours per day. Out of these eleven hours, two hours must be allocated for rest and meals. Sundays and public holidays have reduced work hour limitations.

Domestic workers who do not live with their employers are entitled to slightly different regulations. Their daily work hours cannot surpass ten hours, with two mandatory hours for rest included within that timeframe. Similar to live-in domestic workers, their work hours are reduced on Sundays and public holidays.

The statutory regulations also address work hours for specific domestic worker categories:

• Domestic Workers in Nursing Homes: Their work hours are capped at eight hours per day.
• Child Caregivers: Their workweek is limited to five days, with a maximum of eight hours per day.

In Saint Vincent and the Grenadines, there isn't a single, comprehensive piece of legislation that solely governs night shift and weekend work. However, various regulations scattered across different legal instruments provide some framework for these work arrangements.

The Employment Act Chapter 13.24 indirectly establishes the baseline for calculating night shift and weekend work hours. The Act doesn't explicitly define "night shift" but overtime pay regulations provide some implication.

The Labour Regulations S.R.O 43 of 1985 come slightly closer to defining night work. They stipulate that a minimum night allowance, on top of regular wages, be paid for any work done between 8:00 pm and 6:00 am. The quantum of this allowance is not specified by the regulation and is likely subject to negotiation within an employment contract.

While Saint Vincent and the Grenadines' legal framework doesn't prescribe specific working hours for night shifts, companies can establish shift work arrangements through formal agreements with employees. These agreements should outline shift timings and compensation for night hours.

The regulations provide some level of premium pay for working on Sundays, but working Saturdays seems to be treated similarly to regular weekdays in terms of compensation. There might be sectoral variations, so consulting relevant industry standards or union agreements is recommended.
