You have the Right to Rest! Know your Rights!

This is the minimum amount of days off you can receive. Note: Mandatory training (e.g. Pre-Camp) counts as work so needs to be included in your calculation of how many days off you should get. 

(Scroll down to where it says "weekly or bi-weekly")

An employee must receive at least 11 consecutive hours off work each day. For example, if you are solo in your cabin on night duty til 11pm and expected to supervise the campers, ensure everyone is sleeping etc, then you cannot start work til 10am the next day.

An employee must not work for more than five hours in a row without getting a 30-minute eating period (meal break) free from work. However, if the employer and employee agree, the eating period can be split into two eating periods within every five consecutive hours. Together these must total at least 30 minutes.

Exceptional circumstances exist when:

• there is an emergency;
• something unforeseen occurs that interrupts the continued delivery of essential public services
• something unforeseen occurs that would interrupt continuous processes or seasonal operations

Here are some examples:

• natural disasters (very extreme weather);
• major equipment failures;
• fire and floods;
• an accident or breakdown in machinery that would prevent others in the workplace from doing their jobs (for example, the shutdown of an assembly line in a manufacturing plant).

Here are examples of situations that do not fall under the exceptional circumstances exemption:

• when its very busy at camp
• when an employee does not show up for work
• when an employer has not planned effectively for staffing coverage
• when poor weather impacts programming 
• etc

"Employers and anyone acting on their behalf are prohibited from penalizing or threatening to penalize employees in any way for:

• asking the employer to comply with the ESA and its regulations
• asking questions about rights under the ESA
• filing a complaint under the ESA
• exercising or trying to exercise a right under the ESA
• etc"

Even if you signed a contract or verbally agreed to have fewer days or less time off, this minimum requirement still applies and the camp is responsible for ensuring you get it. 

"No employee can agree to waive or give up their rights under the ESA .... Any such agreement is null and void."
