If you got a raise, you had to really bother them for one, you had to remind them when it was time for an employee evaluation
Once a year
Depends on if the BP is company owned, or is operated by a local operator. I did receive raises based on merit while I was employed part-time.
Often, maybe once every month
Yearly with company and union agreements.
6 to 12 months
They say every 90 days but that is not the case, it is more like yearly
Only got a small raise after a year of service
I think they were yearly, it's been a really long time
