Morrisons Store Deliveries?

I’m particularly concerned about a 13 (potentially 26) week probation period. Seems excessive and the timing of Xmas just smelt a bit. Hence the question if anyone has any experiences of that with them. IE have they got a rep for it? If it’s not a real job, I’ll continue the headless chicken hours pre-Xmas in the run up to the Marie Celeste Jan/Feb period. Obviously IR 35 is a concern but if probation isn’t continued and I’m laid off in January, I’ve lost nothing by staying where I am.

It was a direct application not via an agency; I’ve long since decided all agencies are uncontrollable liars and most can’t count or run a payroll. But they do give the flexibility to tell them to get stuffed when they act like clowns; I’ve zero tolerance for it at my age.
