There has definitely been an issue with Tom's pace generally, but it's not clear cut - the job workload varies from day to day plus also the supervisors often ask him to do little extra jobs which adds more time on (they have done that to me too). I do think he is slow anyway but these issues don't help.

I'm thinking along the same lines as you Seesaw, I'm not sure if my interfering would make anything worse so I'm keeping quiet. Although I very much sympathise with his situation.
