I am terribly sorry to hear of these terrible events your families lives. This dismissal is the last thing you need.
The law is that you are entitled to receive reasonable notice or pay in lieu of notice.
Generally, in determining what is reasonable notice Courts look at several factors including the length of time you worked for the employer, your age, your position, the likelihood of finding new employment etc.
At the high end, if you were in a managerial position, the Court would likely order one month's notice or pay in lieu of notice for each year of employment. If you were not in a managerial position the Court would order somewhat less.
Given that you've worked there for over a year and a half and that part of the time you were in a managerial position that 4 weeks may be a little less than what a court would order.
I suggest that you consider retaining an employment lawyer who can demand another 2 or 3 weeks pay for you. They may agree to pay to avoid a lawsuit.
Does that help as a starting point?
