this may include anything ranging from putting in some extra hours without pay, help to finish work not in your job description, etc.
let's assume this is a white collar office job.
Depends if I think my job is on the line, or if it's the type of employer that actually rewards its employees (bonuses, etc). There's too many conditions possible here. I've had some truly horrible bosses and worked for some shit companies in my time..... and in those cases, certainly not.
