I worked at a company for 2 months when my dad had a heart attack in another province.

As soon as I told them, THEY asked ME if they could do anything to help. Obviously I took a few days to go see him. They were nothing but supportive.

That said, it was also a career job, not an entry level job.

When I was an employer to min wage workers, family emergencies were priority and one had to go back to India for a dying parent. I took their spot 3 days post partum.

Your boss is a dick and pulling a power move.

Stand your ground, and get ahead of the conversation by saying something like "first of all, I want to thank you for being empathetic to my situation. Although inevitable, it's always devastating with the loss of a parent. Obviously, I like my job and want to keep it, and I think I bring alot to the team, so I'm trying to be transparent and honest with you."
