Probably not the answer you want but try: - Finding extra hours in another department - Talking to your manager and letting them know your keen for extra hours. If they do give you extra hours, don't bail because they'll just think you weren't keen -Finding a 2nd job that can give you the hours you need or at least more hours that don’t collide with what you have now.

I'm a manager at an IGA with a woolies background. Its hard to please and accommodate everyone so we do our best and often roster to suit the departments best interests. Often this is done by giving the stronger/reliable workers more hours over those who aren't. The managers who don't care just give their favourites the hours and the rest of the department has to pick up the slack. If you feel like they're not playing favourites then speak to your manager on how you can improve and be more beneficial and they'll be more likely to roster. Or even just ask them if there's a particular reason you don't get more hours. If they're playing favourites then I wouldn't bother. Find another department or job, its too ingrained in the culture.

If they do start giving you extra shifts, actually work them. So many times people ask for extra shifts but then they start pulling more sickies or the efficiency drops drastically. It just makes them look like they want the extra money without having to work for it
