Are Pertemps ok to work for ■■
Worked for BOC & Grundons through them and never had any problems.
The per temps I have worked for are ok kept me in work when needed
The thing that really matters is how good is an individual branch. Asking how good the whole company is won’t help much. From what I have seen their advertised rates seem to be lower than average.
Back in 2008,following the big crash,they got me fixed up with a temp to perm after 3 months on the dole (for the only time in my life).Must admit I’ve got a soft spot for them 
Mind you ,it was delivering bread
