I have been on LOA for covid 19 and I woke up to have my manager Mike st. john calling me informing me hes terminating me.
Thats beyond screwed up, I can't leave a message with anyone else about this issue either.
He flat out lied to cover his own butt.
Saying things like I was hostile towards multiple managers however he is the only one I talked to.
I have friend who are overworked and verbally abused by these managers everyday.
I can't believe there are people like that at these stores abusing workers at will.
The open door policy is useless because management cover eachothers butts so any complaints go unnoticed or they just get rid of the "problem"
