GeordieGreigsButtButtZoom: You keep trying to blame part timers for the fact that management hires part timers. It is like blaming a juggler for being employed at a hedge fund because their juggling skills aren't useful to the company or compatible with the low-hanging chandeliers.If the type of work on offer isn't beneficial even when the workers do the job fine, management shouldn't be deciding to pay people to do it. It's a management issue. If a woman asks to go part time after having baby, again, it's up to management to make the call. If they think she's a great worker and want to keep her by allowing it, that's up to them. She obviously impressed them enough as a full timer and presumably remains accountable.
Part time work is notoriously difficult to come by, partly because it often is not compatible with a business, so I'm grateful that I'm able to do it. If anyone has a problem with me being part time, they need to speak to the board. The position was advertised as part time. That was their business decision, not mine.
I don't think you get it. I am not blaming pt-ers. I will happily phase out your rare pt job because I would rather not have to accommodate your hours however good you may be. Bear in mind pt-ers stay for years pt (which is years of accommodation and inconvenience for the employer) but if the employer fires you and hires a ft employee, they only take a temporary hit in training and end up with lower overall costs and hassle of a ft employee.
If every employer behaves like you expect them to (and not accommodate pt-ers who are good but whose hours are less than ideal for the business), isn't that a retrograde step? You are cutting off your own nose to spite your face.
With the best pt arrangements and the best management, you cannot control what other people think. Of course, some people will be resentful for reasons which may be entirely unjustified. Just quit or grow a thicker skin or blame management, it seems.
