Pros

Only pro is you can have lunch whenever you want.

Cons

This company has no respect or integrity for staffs safety or understanding for uncontrollable inconveniences. If public transport has delays and you’re late, expect to have your position unfairly terminated without them taking into consideration it may not be your fault. I have videos and pictures of the sites Trinity had me work at, which all have had bed bugs, rats, mice, flies and other such dangerous and contaminative environments that could cause diseases which is not safe and was not discussed. Worst Locations - Ridley House - Hostel - (Dalston Junction) Northumberland House / Cape House - Hostel (Tottenham) If i could go back and stop myself from applying to this position I would. It’s not worth it. Find something better, your worth more !!
