Can I get fired if I call in sick within my 3 month probation peroid working as a waitress

Your employer can terminate your employment at anytime so long as they provide you with the appropriate amount of severance. Please visit the severance pay calculator our firm has developed for further information on the amount of severance you would be owed at termination (www.SeverancePayCalcualtor.com).

Given your circumstances, your employer could terminate your employment without paying severance if there was an employment agreement where you specifically agreed to a 3 month probationary period. That said, if they did so because you called in sick it could attract human rights damages. If you are ever terminated, it is always best to consult with lawyer before singing anything.
