Just a quick one really. I work part time in retail and I'd like to ask to increase my hours by just another 6 hours a week or so.
I'm wondering whether to ask my Manager informally first, or is it best to put a formal request in?
There's usually overtime, but I've noticed only certain colleagues seem to be offered it, which I find unfair, especially as there's been no issues with my work performance, and I've been at the company longer than most.
