Apparently I misunderstood. It's not company policy that they don't work after a session, he just had an absolutely awesome manager. He emailed his new manager yesterday about needing his shift covered and got "why do you need it covered when you don't start while 7pm?" Hoping it's just because he's naive and has no experience of mental illness as he'll come unstuck if J gets the union involved as they'll just threaten to have him signed off on sick until after his sessions are finished...
